No... you simply can't take a low kv. inrunner (low pole) and run it at the voltages we use, and expect to get decent power from it.
You 'could' get a quite large inrunner, something at the very least a 1527 motor and run it way under powered (for it's size) to get the right rpm out of it to be used on the tranny. I can't really tell you how efficient this would be though.
IMO, the way to do this, is to use higher pole motors (which has higher torque lower rpm, but same power output as similarly sized inrunner) and go directly onto the diffs.
Or, if what you are talking about Hickoryhead, try and find an appropriately sized outrunner and go direct drive to transmission, but I see little gain doing this, IMO.
This is a territory no one has really been yet... it makes things interesting.
