The Turks seem to make every possible type of shotgun.  With the popularity of the SPAS-12 in media and games - Is it possible you could get your Clone makers over there to do a version of the SPAS-12?  Yes ots really a clunker of a gun - doesn't stop the bear $2k prices for them.

Even if the makers could make a version that was semi-auto only and simplified the mechanism and just kept the overall outside look of a SPAS

That's a cool idea. While they're at it, ask them to clone the Benelli M4 collapsible stock. All the ones Turk ones currently on the market look too far off from the Benelli one.
