I'm sorry dude, but I have to tell you, Monero people overtaking Bitcoin people on Nostr is just not going to happen. Nostr is maintained by a bitcoin core contributor. Most clients have lightning network integrated, as does the protocol. You're just not going to try to overtake Nostr without creating a whole separate network of clients and relays and a different protocol specification to remove the LN and potentially integrate Monero.
Now, there are a lot of shortcomings in Nostr. The core protocol design is solid. But the design philosophy of "add what the community wants as needed, move fast damn the outcome" is a bad approach IMO. A well thought out set of design principles (while being use case agnostic) is what's needed IMO. If I were a part of your organizing, I'd agitate to create a different protocol spec, and I have a rough idea of how such a protocol would look. It would look a lot like Nostr, it would have encrypted messaging as a first class citizen so that even relays couldn't read your messages, and it would not have so many different message types (basically one for recipients and one for relays). All the extra stuff like verification and LN would just not be there and be left to the use case specific client design.
