Ideas for new Prime and Megs VAs

If you could choose two brand new professional voice actors to voice new versions of Optimus Prime and Megatron, who would you pick for each?
The trick here is that you cannot choose someone who has previously voiced either Optimus Prime or Megatron (or Galvatron). Meaning that Peter Cullen, Garry Chalk, Neil Kaplan, and David Kaye are not optional for Optimus Prime; and Frank Welker, Leonard Nimoy, David Kaye, Garry Chalk, Daniel Riordan, Neil Kaplan, Richard Newman, Trevor Devall, Hugo Weaving, and Corey Burton are not optional for Megatron/Galvatron. Same goes for anyone else who has voiced Optimus Prime and/or Megatron/Galvatron.
My choices would be:
* Optimus Prime - Kevin Conroy (Batman in the DCAU)
* Megatron - Jim Cummings (many character voices, but specifically Dr. Robotnik from SatAM)
EDIT: New rule: You also have to say what character(s) these voice actors have previously played.
