Why wait around for "better" (allegedly) superheroes to get called up when you've already got these on deck or in the batter's box? Play 'em, coach.
Maybe I'm missing the GA clamoring for more Falcon (how is that possible?) and WM. Could be, but I haven't seen those sentiments out in the wild. I still hold that you go for better over what's more convenient.
And for the record, I'm not saying that Widow should go. I think you should add BP and Danvers ahead of WM and Falcon. They're more powerful and more interesting, which trumps familiar any day of the week. It won't take long for people to fall in love with them.
