Truthfully you don't need very many weapons in the game. Most of the distinctions are fairly arbitrary. You need basically a dagger, an arming sword, a bastard sword, and a full two-hander. Then you need what? A club/mace, an axe, a hammer, a flail, and two-handed variations thereof. Then you'll want a spear, and a pike for spears. A poleaxe, a glaive, and maybe a fork. One and two-handed staves round things out. That actually covers all the basic forms of weapons.
There are some minor variations, like slight variations on chain-type weapons, a few variations of swords and daggers (back swords and sabres, punching daggers, etc.) but those ESSENTIALLY function in nearly identical ways with the more conventional variations (which probably explains why they've never been very prevalent).
Probably won't be duplicating missile weapons ... but I might do something with the sling where you do snap throws which allow one to gain the reach and range of a sling (oh look perhaps a martial art for bilbo).
Staves and Chain weapons have a tradition of direct use by the "martial artists" so I might not do techniques which count as those... but a drunken monkey martial art might use chain flexibiity in its attack techniques so I might still use it.
