Would the exodus seed containing xmr work with feather desktop wallet if i backuped to feather?
Yes, I don't see why it would
ontnot. This would help you recover all of your assets (if you have any) and not just Monero. But if this is a wallet you have been using for a long time, I would personally feel more comfortable creating a new wallet in Feather, and recover this one... and then send the recovered one to the new wallet you created.
