Did it years ago (before MC28 existed) and it was alot of agro.

RVF swinger has offset shock (not central like NSR) and different shock linkage mounts. You'll need to cut a section of the shock tunnel out and reweld a plate in. Then you have cut off the shock linkages mount, have a new one machined and then weld that on. Finally I seem to remember the rear wheel needed a spacer too to get it to line though.

Best get yourself an MC28 swingarm, seriously!
