Question '83 flywheel and clutch "Plug N Play" on a '78???

Inspired by a reply in this thread I thought I'd start a new one to specifically find out what is involved.
It caught my eye because I have a '78 R100/7 and also a '83 R80RT parts bike and have been interested in lightening the R100 flywheel.
Could this be nearly as simple as a swap out?
I'm noticing a fair amount of false neutrals especially from 3rd to 4th and 5th to 4th, 4th to 3rd which having a spare tranny/clutch on hand makes me even more intriqued.

Is it a simple parts replacement process? Buy the late model clutch carrier, clutch plate, etc., and "plug-n-play"? Any machining involved?
