I am currently doing this myself. I am putting an 01 engine in an 02+ frame. The swing arm and lower mount work out fine. The front mount needs to be drilled and the head mount needs to be fabbed. I am mostly swapping just the frame and sub from an 02 and using all 01 for the rest of it. I am saving all the 02 bits for my 500 conversion. Let me know if you have any other questions. Here is a before and after, It's not done but mocked up.

PS you WILL need a 02+ silencer (01 header works fine) and rear master cylinder.

will the '00 swingarm work on the 02+?

01 swinger will work fine, same with the shock. If you are to run a 02 swing arm with an 01 linkage you need to swap out a part of the dog bone as I believe the swing arm tabs are smaller on the 02.
