There is a chance. No, I'm not working on one now. I spent a lot of time working on Mosaic, which was how I proposed fixing the hard problems like NIP-65 not being good enough, relays wanting multiple IP addreses and maintaining reputation when they move IP addresses, ditching trust of DNS, improving performance, and a whole host of other minor tweaks of nostr including using different cryptography (a prereq of solving at least 2 of those problems). I couldn't seem to both solve these problems and also make it backwards-compatible with Nostr. I got pretty far, but stopped before I got close to the finish line because, honestly, my motivation was drained (nobody came along to help me). Then I got myself involved inother things outside of nostr.
