It's definitely versatile and has many uses, but Velvet will never be as good as the original wielders of the weapons. The weapons take years to master and learn how to use effectively. They also complement the person who wields them. Velvet's movement imitation is simply not enough to fully utilize the weapons. For example, it's highly unlkely that Velvet could use Weiss's Myrtenaster to summon.

As for Velvet's death in Volume 6, I think it's possible but unlikely. We can't even be sure that Team CFVY will even be in it. Considering that Velvet is such a minor character, it would be pointless yet easy to kill her in Volume 6.
