Manifest Weapon suggestion

I've read a few threads on how to make this ascendancy skill useful and would like to add.

Currently, we can use 3 types of melee weapon for manifesting (Mace, Spear, and Quarterstaff) with their own skills, namely "Slam", "Lunge", and "Sweep". Since it has its own skills, why not make Manifest Weapon manifest all three of them, maybe put up some kind of an "inventory" like on Titan ascendancy "Colossal Capacity". this will make use of the weapons inside that "inventory" making warriors use the unique weapons on Manifest Weapons but use different weapon for both main and offhand

this may not be applicable in the future since all weapons is not yet released but it would be a good concept still.

Then again, this would still fall to that one thread I've read, that make it manifest more or just make one useful and big weapon
