I'd love to see someone fork the existing client and swap out the lightning zaps for #monero zaps.
maybe that's another good crowdfund idea...

There have been some in the past. They all kind of died off though. Garnet, Amethyst fork, was probably most promising. I think someone forked Nostrudel as well for desktop.
