Differences between KTM 1050 and 1290 superduke engines?

So recently I was left alone with my thoughts for too long (this is often dangerous)

I came to the thought of if it was possible for a person to buy a KTM 1050 adv and if they lucky enough to come across a written off 1290 superduke that they could then swop the 1290 engine into the 1050 frame with as little changes as possible.

This is all hypothetical nonsense (or is it?)
But a do it all bike with 180hp sounds good to me.
