I like to think that, as the years go by and they see the happy family being happy, at least SOME of the Overwatch members start warming up to Sombra. Just a lil.

Possibly? In my personal headcanon, Sombra has no interest in joining Overwatch or interacting with any of its members, ex or current. The only person she might have some contact would possibly be Mercy and Genji because of McCree. 

It’s hard for a lot of Overwatch members to ever get over the emotions that come with Talon – after all, they have killed a lot of Overwatch and Blackwatch agents. Even if she wasn’t truly with them or agreed with their ideals, Sombra still willingly joined them and isn’t innocent herself (Winston and Tracer come to mind). They’d keep their guard up – they’d be happy for McCree and glad that he’s not being taken advantage of or manipulated. And they’d definitely warm up to his kid(s) but Sombra is a completely different story. But Sombra doesn’t care what they think of her and she’s not looking to make friends with them either.
