What we ended up doing was providing our determination to the borrower's insurance company and getting them to amend the policy with the appropriate listing and premium rating. If it was A vs AE or something, not as big of an issue, as I understand it, but A vs X is an "in" vs "out" thing for bankers...
As my sig says, this is only my opinion based on my exam in October from OCC - Central District. Your prudential regulator might look at what you've got and be OK with it as you have coverage way above required level and are tracking it.
