If you have the proper tools and having everything formatted correctly it should be possible. You can edit them in pikahex without much issue, so the saves themselves are probably identical structure-wise. The real issue so far is that none of the current homebrew save extractors can break their encryption, so unless you have kernal access, you're stuck anyway. Fortunately, gen 1 is so borked that unless you have some people that want to battle with you there's not much need for save editing anyway. The game itself isn't that difficult.
