Kensai Signature Weapon question

[BlackSeed_Vash]

For those that dont have CWar or do not have it handy; here is all info on this class feature san the Losing a Signature Weapon portion and the table showing the max enhancement bonus per level/xp cost.

Signature Weapon (Su): The Kensai chooses one of his weapon (it must be one for which he has the Weapon Focus feat) to become a signature weapon, but even a kensai's natural weapons can be chosen. If the weapon is a manufactured one, it must be of at least masterwork quality.
Upon qualifying for the class, a kensai gains the ability to estabish a link with his signature weapon. The character focuses part of his lige energy on the weapon, making it more effective in his hands and his hands alone.
The process for imbuing a signature weapon with power is a simple one. The character must find a quiet, safe spot to meditate (and pray, for those kensai who serve deities) for 24 hours. At the end of this meditation, the kensai sacrifices a number of experience points, essentially shifting some of his lif force into his signature weapon. The signature weapon then becomes a magic weapon (if it wasn't already) and gains an enhancement bonus and/or special abilities. His current class level limits the amount of enhamcement a kensai can place into his signature weapon. A kensai cannot creat a signature weapon if doing so would cost enough experience points to reduce his character level.
Use the table on the previous page to determine XP costs and class level limits.
If the ritual is interrupted, it can be begun again at any time, but it must run for a full 24 hours for the signature weapon to be imbued. The kensai pays the XP cost as soon as the ritual has been completed.
A kensai's signature weapon has a caster levle equal to the character's class levle +10.
"Imbuing Double Weapons": A double weapon may be imbued, but both ends of the weapon must be paid for and imbued separately.
"Imbuing Natural Weapons": The process for imbuing a kensai's natural weapons (such as his fists) is the same as for a manufactured weapon, except all of the kensai's natural weapons of one type are imbued at 100% of the cost +10% per natural weapon. For expamle, a human kensai who has Weapon Focus (unarmed strike) may turn his fists into signature weapons for 120% of the XP cost. A six-armed kensai with a bite and tail attack would have to choose between fists, bite and tail and pay either 160% of the cost (for six fists) or 110% of the cost (for the single bite or tail). A kensai' who imbues a particular type of natural weapon must imbue all his natural weapons of that type (so a human kensai with two fists must imbue both fists). It takes 24 hours for a Kensai to imbue one type of natural weapon, regardless of how many actual weapons of that type he possesses.

What I would like to know is if it would be overpowered and/or against the Prc concept to allow a second weapon (or natural attack) to become another Signature Weapon?
The only reason my player and I think it should be fine is due to the underlined portion about double weapons.

Also, for singular a natural attack with multiple parts (hands, feet, etc), would it be overpowered and/or against the Prc concept to treat as a double weapon? What I mean is something like "left hand" is +1 Flaming unarmed strike and "right hand" is +1 Last Resort unarmed strike.

If I were the DM, I think I would be happy with you splitting the limit across two weapons, but not allowing two weapons each at the maximum.

If you know what I mean

I'd allow each to have up to 3/4 full power... but you get to pay for them seperately. This would allow for a dual-wielding Samurai's daisho or a Drizzt-clone's dual-scimitars.

By RAW, you're stuck with one weapon, a double weapon, or a (single) natural weapon.

While it's clearly a house rule, I'd let a Kensai enhance two identical weapons to the full power limit, while paying the full XP cost for both of them.

The identical restriction is mainly for flavor reasons, since it's his signature weapon. It also prevents the (minor) abuse of something like Morningstar and Dagger, so that you have all three types of damage.

I'm hard-pressed to think of a situation where fighting with two weapons is superior to fighting with a double weapon, especially when the two weapons are identical. Two weapons cost the same, they are probably light (so no power attack) and if you only get a single attack, you get 1x strength damage, not 1.5. Plus their easier to disarm and sunder (since the generally have fewer hit points).

The up side of two weapons appears to be that if they're sundered/disarmed, you still have the other weapon to use. Actually, there's also the fact that (if they're light) you could use one in a grapple.

I think that the spirit of the RAW is against the idea that a Kensai could enchant muliple weapons differently. In fact, if I were a monk and the DM let me do that, (and enchant multple body parts), one knee (or maybe elbow) would be something enchanted for damage. My other hands, feet, elbows, knees, and head, would all be +5 defending (maybe each with a different bane echant weapons. Since the AC bonus from a defending weapon is unnamed (I think), you can get HUGE bonuses to AC from being a 6 armed Kensai =P.
