If you look at pictures from early Stephen Collins roles like Brinks: The Great Robbery and The Rhinemann Exchange (a great opportunity if you want Larry Hagman to play an Admiral)
he doesn't change that much physically in the few years between those projects and TMP so if you are planning a photo of him as a cadet you might as well recast him or adjust his current TMP look to be honest.
Perhaps the title needs a change for it to fit in with the series.
I'm reminded of the quote "Be the maker or let the maker be".
Let The Maker Be sounds like the sort of title an OS episode might have.
