While I don't think that there will be any issues, you have to be careful when moving some of the core aspects of the phone because they can be tied together sometimes.
I would suggest rooting the note, renaming the touchwiz email app, not deleting it, and trying the other email app. This way, if something goes wrong, all you have to do is delete the new email, and return the touchwiz email back to its original name.
Hope this helps.
