Not up to me. But Bisq is FOSS: anyone can make a proposal on github for that. (of course you then have to find a dev willing to work on it, that's the real hurdle).

Are you in contact with Manfred or know if he has a presence on nostr? I think it would be good to have some insights into the inner workings of bisq before starting a proposal. @Deleted account

That's basically what Haveno is supposed to be (whenever it's completed...) haveno.exchange
