question about interchangable parts beween 02 and 03 yz

I have a quick and easy question hopefully someone well know. I've been wondering this a long time. I know people swap the 03 exhaust cam into the 02 426 to get rid of that dang decompression lever. However, can you put a crank of an 03 450 into a 02 426?

... can you put a crank of an 03 450 into a 02 426?
..No.
..No.

This is do to the fact that the 450's stroke is longer.
