People ship absolutely any two characters, and will 100% due it if there are two attractive opposite-sex characters of roughly the same age.
Sure, there are bound to be some people whose minds would go there, but they're surely enough of a fringe group that I don't see why they're even worth bringing into the conversation. It's a really distasteful thing to bring up for no reason.
Regardless, there was fundamentally no reason for this to be Scott's movie, when you consider the point was to find a way to introduce a Kang variant into the story to build up the menace for later.
The reason was that it defied people's expectations. You think that's a bad thing, but I find that attitude a failure of imagination. I actually love the idea that this ultimate, all-powerful big bad was defeated by the last guy anyone would've taken seriously as his nemesis. Indeed, that was part of the point of the story, that Kang never imagined that of all the Avengers, Ant-Man had any chance of taking him down, so Kang was defeated by his own inability to look beyond his preconceptions. It's right there in the title of Scott's book -- Look Out for the Little Guy. That doesn't just mean to be considerate of the little guy, it means not to underestimate him.
