If they were going to do a multi-model cover, I think the only way to do it would be to focus on the girls who are killing at social media. "The New Supermodels: How Social Media Has Given Names to Today's Faces of Fashion" The ones who are on the fashion blogs and the gossip blogs and partying together and who have millions of instagram followers, etc. Essentially, this era of "Supermodel".
it would have to be the gang of girls that all kind of flock together and seem to genuinely be friends with one another.
Cara, Joan, Karlie, Liu and Jourdan. They're the ones making the best use of social media to further propel their careers and so would be relevant for what could actually be an interesting cover story. If they wanted to get another "Angel" in there, they could add Candice to the mix as she's extreeeemely popular on instagram. Or if they wanted to get even more attention, they could add Miranda as well. She's pretty much a household name at this point and aside from her famous husband, much of that is to do with her ubiquity on social media.
