I tried nowser! Doesn't seem to have external signer capabilities. It works great to sign event on nostr:nprofile1qqsqyjs7pnjprunh0r7sa922ynzndrp7md4fydszx8agljca2qlgxugnxnewj web but it doesnt allow to use external lightning wallets and doesnt have an internal one :(
Do they have a nostr kind0 you can tag?
