I think more than 1 of these M.I.A. characters, if not all (in the the poll & beyond), stand a good chance of appearing in HOX, POX, or both. That's due to the promise of the premise(s), the nature of these stories that will be told & their presumed epicness, and what's been said about them. In fact, I'll repost some speculation I indulged in previously, that theorizes we might have already seen a few of them:

But also the metal dome, and the belt with pouches besides, that's similar enough to big daddy Mags' in HOX. The uniform in general, bears other resemblances to his, as well. With him it's not only by association with her, but the hair & outfit colors, along w/the sorta glowing yellow eyes.
