I don't think reusing XPUBs inside different multisig wallets is a good
idea... For starters, loss of privacy in one wallet will immediately affect
privacy of other wallets. I think multisig wallets should be completely
firewalled from each other. That means one unique XPUB per wallet. This is
what we have been doing with the Nunchuk wallet.
