Swapping Dash Board & Door Panels, Older To Newer E350/E450

I was talking about replacing the entire dash board, steering wheel and all. Not picking and choosing parts to stay and parts to swap. I may even need to swap the a/c & heater core box and other things mounted to the fire wall, but I hope it doesn't get that complicated.

I assume an E150 donor interior is interchangeable with an E350 cut-away interior. I can't imagine there being any differences except maybe a rear heater control and other related things that a cut-away won't have.
