I'd love a Jason Strongbow American Eagle. "Marvel Team-Up" and "Marvel Two-in-One" were (and remain) some of my favorite comics as a kid, so American Eagle looms large in my memory because of how much I loved his first appearance. Plus he's in the first few pages of every handbook released since his debut, which has always kept him in my head.
Catching up from the past couple days, absolutely yes to Jeff Mace Patriot, though not on the top of my Golden Age want list. Super-Patriot would be cool if we got Captain America-specific characters more often. Probably a pain in the ass to do deco for, though.
And yes to Reb Brown Cap (Big McLargeHuge!), as well as the serial version from the forties. Most "never gonna happen" Marvel Legends figure of all time, honestly hadn't even thought of it until this thread ... but now I really want one. Give me Tom Tyler Captain Marvel, too!
