i don't think anyone actually knows the answer to this. both transmissions are equal in terms of cost and availability so there's lacking reasons to attempt it.
if you wanted to investigate you can compare wiring diagrams. if the pinouts are identical - that's a good sign it'll at least run and work.
VDC is really a controller difference - it controls the engine, brakes, and transmission. the engine and brakes are the same/interchangeable in VDC and non-VDC vehicles so really good chance the transmissions are as well.
after that - start comparing parts:
1. front differentials are the same - same final drive ratio so that good.
2. valve body
3. rear extension housing guts (both are VTD in the H6's right)?
but again - conjecture.
