What do you guys think about these second-tier Avengers in the MCU:
Moondragon
Wonder Man
Spectrum
Sentry
Moondragon would be great to introduce in Infinity War as another of Thanos' 'daughters.' Thanos had the Mind Stone, until he loaned it to Loki, and it can explicitly create superhumans (like Wanda and Pietro), so it would be entirely on-theme for a psychically-potent Moondragon to serve as one of his daughters, at first, until, like Gamora and Nebula before her, she turns on him. If she's the supposedly-dead daughter of Drax, so much the better. (What, Drax has a daughter supposedly killed by a dude that we increasingly are finding takes little girls from his slaughters and raises them as his own 'daughters?' How convenient, from a storytelling perspective!)
Wonder Man would be potentially interesting, as well, although I'm not sure what he'd add, at this point. Without his relationship with the Vision, Scarlet Witch and / or Beast, he's missing a lot, IMO. (Although a variation in which he's the fragmentary surviving consciousness of the Vision, after the Mind Stone is plucked away from him, manifesting in a new organic body, after the destruction of his original vibranium-infused body, could be an interesting way of utterly reversing the comic book origins of the two characters.)
Spectrum/Monica Rambeau would be fascinating and I'd love to see her, although I have no specific idea how she'd be introduced. Vaporized by the Power Stone and then reforming as a creature of energy seems a little too pat, and, IMO, the Infinity Stones are getting enough of a workout already.
Sentry, meh. The MCU needs a Superman-clone about as much as the DCU needs a Spider-Man clone.
I wouldn't mind seeing a few others lesser-used Avengers. Black Knight, for instance, might make a neat Netflix hero.
