Your number sounds very reasonable to me (I don't know that Vertex longs would agree :-)). My wild guess is they want it to sound better and get it closer to 200M+ by perhaps tagging along some shares either straight out or more likely on a delay/non approval.
I would think this is right up Royalty Pharma's avenue. Maybe they would even buy out their whole EU stake if VRTX really is hard out for cash :-).
