I'm looking for someone to sculpt me a Vortex-esque head that would fit the neck joint of leader class animated megs.

Also, but not nearly as important, any ideas on how to customize a voice modulator for the animated megatron base figure for my custom?

After enjoying some of the artistic works of some of the fandom's great's I've decided to try my hand at kitbashing. However what I'm looking for will take some outside help (as in the request above) in order to acomplish my vision.
