Random Idea: What's the chance I could use Crona's kid as a Weapon who creates a copy of his/her weapon form out of Black Blood so his/her Meister can dual wield?

EDIT: Hell, I might be able to do the same thing with a Meister!Crona kid, except for his/her partner. Then again, that'd restrict him/her to a one-handed weapon with a fairly simple design, no guns or nothing.
