Heck, I don't think Sam and Berto would have been in consideration for the Avengers had they still been "kids." Yana is a bit more fluid in that due to her being pulled around in time and space constantly, but she also shows up in the far far future as Sorcerous Supreme looking only slightly older than she does now (meaning that she uses Magik to manipulate her appearance a bit even today).
