That sounds good if it works.  However ... will an add_missing_from view work 
if add_missing_from is off in the session where the query is executed?   If 
not, then I don't really find this  a solution.  In that case, it would be 
better to supply a script that allows users to find add_missing_from 
dependant views so they can fix them.
