Why not?

Driveshaft length.

So, it would work as long as u made some custom length dogbones?

Yea it would work if you made a new dogbone.

Maybe we should take a count and see how many people would buy a "direct drive" one with just center diff and teh motor driving that. Kershaw might make them if there is enough interest. I know that I'm interested in getting one for my BL Savage XL. I dont think dogbones would be a problem, once you get the measurements you need, I bet you could find some.
