Use identical motors, and just parallel them - you obviously need a speedcontroller twice as powerful though.

I would suggest you check out the Robot Wars machines, and see which ones worked, and which ones didn't.

THese are just brushed motors so you only need one ESC for all motors spinning in the same direction (ie. on ESC per side as long as it's big enough to handle the current of all motors on that side).
