Red Wolf and Spitfire are both an emphatic yes from me! Both classic, but that's de rigor for me. I functionally collect like Marvel stopped publishing after its mid-90s bankruptcy.
Red Wolf is one of the biggest gaps in our Avengers ranks. Classic is the only version I want, though I've always been concerned that the look and name might give Hasbro pause.
Spitfire is one of my favorite golden age (retroactively) characters, she'd make a great figure. It'd be excellent if we could get an improved Union Jack to go with her. The old figure is really showing its age, and Jack needs to be super poseable to better do battle with Baron Blood ... who we also need.
