Look, AFAIK, the current multisig wallets don’t allow removing/adding cosigner while preserving the same key that was originally generated. That said, there is flexible round-optimized schnorr threshold signatures technique that makes this possible. FrostSnap developers employ this technique at developing their product, thus, we might start seeing such wallets in the near future ^{since a working prototype already exists and the developers are actively moving the project forward}. If you're interested in the details, check out this thread to learn more about frostsnap.
