Even if he did that I'ld be in the same boat as a fighter.. don't loose your weapon, and you've got no problem. But I was thinking more along the lines of what you see whenever you're at a martial arts tournament, or watching tv/movie, etc, when you see a guy/girl with a staff. Kick, staf staff, punch, twirling trip, etc. And the staff usually does as much damage as the rest of the attacks. It does make sense, too. I'ld be willing to give up the monk 'bonus beats' that give the choice of 2 feats, or something like that.
How about two new feats?
Armed Trip
Prereqs: Improved Unarmed Strike, Improved Trip, proficiency with selected weapon
Benefit: Choose one melee weapon. You may now use it to make trip attempts.
Weapon Kata
Prereqs: Monk level 8+, Weapon Focus (selected weapon)
Benefit: Choose one monk weapon (any weapon that can be used for a flurry of blows). You may now deal damage with this weapon as though you were a monk of four levels lower fighting unarmed.
Which, at tenth level, would mean a d8 with a quarterstaff instead of a d10 -- mainly for balance reasons, to offset the availability of enhancement bonuses to weapons, as well as the way this compares to the abilities of other classes -- at 10th level, it's statistically a +1 to damage for virtually all monk weapons; this compares unfavorably to Weapon Specialization, as it should, because that's the Fighter's unique privilege for a reason. It catches up with Weapon Spec at 12th level, which by no coincidence is when the fighter becomes eligible for GWF...
On the other hand, if you want a quarterstaff strictly for style points, I'm open to the idea of a "bonded weapon," specially hewn and crafted... It would have to be at least masterwork, and could be used (in a given round) either as a quarterstaff normally would
or as an "extension of the body"... In the latter case, it would function mechanically identical to your unarmed strikes (you'd lose enhancement bonuses, no 1.5x str to damage if you're only making one attack, et cetera -- basically you're considered to be fighting unarmed, it just happens to be that you're holding your special quarterstaff in the process.). In terms of functionality it would be liked getting a limited quickdraw feat for free -- since this is still a benefit, I'd say you'd have to trade in proficiency with one other monk weapon (kama, siangham, et cetera... not much of a penalty, but it would come up mechanically about as often as the quarterstaff change would..)
You can go either route, and I'll consider both of those feats open and available to all. If neither option works for you, feel free to suggest another.
