Martin,

what Phil is saying works exactly as described and a very good idea. 

Just a caveat:
The safest bet for this method is to limit layers to adjustment layers and masks. 
If you use pieces of the image and channel calculations and the like, you'll 
have a hell of a time replacing all the pieces with the same taken from the raw 
scan after resing up.
