Colin,
1) This is a good start for a BIP, but it's missing details. For example,
the nonce is encrypted by the server. What key is it encrypted with?
Clarifying ambiguities like this can sometimes reveal weaknesses that you
wouldn't otherwise think of.
2) What kind of recovery questions are

Would you then assume that userWalletPubKey is a hot key
I believe I have come up with a structure that allows for trustless use of
hybrid wallets that would allow for someone to use a hybrid wallet without
having to trust it while still allowing for emergency recovery of funds in
the case of a lost wallet. It would run off of this TX script:
IF
1
