The far greater concern is with the privacy. Any attacker with all of the master public keys, will know all of the possible addresses generated that can be generated with your multisig, provided that they also know your derivation path. The latter should be a given, any complex and non-standard derivation path could result in the user lose all their funds if they don't save it properly.

Unhardened keys will let an adversary be able to obtain your master private key with your master public key and any individual public private key from that keypair. This shouldn't be a problem because you are not supposed to expose any of your addresses anyways.

Probably not the best idea even if your need more than one of them to spend.
If your going to the trouble of using Multi-Sig then why keep the keys online?
Seems pretty stupid.

For multisig you have to have all Zpubs in order to spend. What are the risk associated with savings your list of Zpubs on google drive or the likes so that you can access them from anywhere.
