Overdeveloping Pan-F is a Really Bad Idea because it rapidly becomes unprintable.

The only way this is going to vaguely work for you is to use a 2-bath developer, e.g. Diafine. Those are mostly time- and temperature-independent because the total development activity is a function of how much of bath A is absorbed into the emulsion before being activated by bath B.

Much simpler to just develop each film-type separately and correctly for the particular SBR that it was used with.
