We already have some Amazing champs as 5 stars, but will these EVER be added?

So, we have some of the most desirable champs in the game as 5 stars. Champs like Starlord, Iceman, Gwenpool, Archangel, Stark Spiderman, X23, Doctor Voodoo and Hyperion.
So, what difference would it make if we went ahead and added the ones that have been held out forerver:
Vision
Thor
Black Widow
O.G. Daredevil
Wolverine
Captain America WW2
Doctor Strange
Scarlet Witch??
If it's because they are deemed "Too Powerful", could they possibly be anymore Powerful than 5 star Stark Spiderman or Starlord??

Doesn't make sense with alot of the champs that are in it but there you go
It would be nice for them to "reconfirm" this so people know the 4 star versions will still be viable for awhile.
