Unfortunately BTC's high fees discourage its use. Monero is like 80% of all trades in bisq. Why not make it a base currency, too?

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.
