Sinister doesnt age right? so there you have it.
He uses young Jean and Scott on the 80's, and back to present, he tries it a second time. Perfect arc for him on the franchise.
Posing the question again, why go through the trouble of looking for new talented leads for a 1980's backdrop if you are going to cast them aside in favor or X4-5? Ideally, yes, fanboys would love it. But it's not practical from a business end. Now if you filmed all three movies back to back with the same director like a LotR trilogy, then you wouldn't have that problem worrying what becomes of your FC3 cast. Wishful thinking. I want them to do exactly what you propose. But I don't see it happening. Nor did I see DoFP happening, so anything can happen.
