How difficult would it be to merge a V8 hp70 with the active hybrid version to make it exactly the same as the V8 transmission but in the inline 6 compatible case?

The goal would be to remove the active hybrid bits and make a "hybrid" (pun intended) of the two transmissions in the active hybrid case that bolts directly to the N54/N55/S55 including having the more standard clutch configuration you mentioned, etc.

If I had 8hp70h and an 8hp70 from say an n63 car side by side what would it take to essentially remove the hybrid parts and swap in the standard parts so that I get the right case?

Would all of the parts from the N63 version swap over? Would they both have to be Xdrive or RWD versions to be compatible or are the tailshaft differences not important?

I would just run an adapter plate but the N57 RWD 8hp70 seems even more rare in the US than the active hybrid one.
