As vocal as I might be about wanting the rest of the Ware cast to get more love, I honestly wouldn't be opposed to a Ashley game, after all I do still like her.
With that said I don't think that her recent exposure makes a Ashley game any more likely, people said the same thing about Rosalina when she first started to become more prominent and I have seen folks unironically predict a Rosalina game announcement for E3 2014, only for Toad to step in and say nope Treasure Tracker is better then any potential Rosalina game anyway.
I wouldn't mind to be proven wrong thought, because as I said before, I'd be fine with Ashley getting a game.
