buy a slayer sell nitro engine and then by electric conversion kit. I think hot bodies still has a 10th scale 4wd st but it also would have to be strecthed and converted to electric. Or you could go all out and build it like a crawler, but get a hpi mt2 front independent suspension and get a solid rear axle and ad a swing arm type suspension. Then get a rustler transmisison run some drivlines to front and rear. Good luck on chassis design and the rest of the peices. I've wanted to do this but never went for it.
You could use a Wheely King axle for the rear. Its beefy and uses the same diffs as the MT2 so you dont have to worry about different diff ratios.
good call on the diff ratio I didnt think of that
