For me the scholar-archaeologist would be my second mc, who is with Max. 
While such a thing would be nice I’d be happy with just a patch in the epilogue that would allow the mc to possibly accept Max/Delacroix or Rosario’s help when they offer it, instead of being forced by the game to turn it down, just something anything to indicate the mc might not suddenly be a-ok and entirely back to their old, dashing, selves again in just a couple of days after being forcibly indentured for weeks or months. 
I’d still like a possible (royal) wedding DLC, would at least allow the series to end on a high note for my mc, instead of the current bittersweet one.
