Provided they were not rehashes of existing figures in same costumes I would be willing to pay up to $200 for a five pack.

There are so many women of Marvel needed!
X-Men, the five mentioned as well as Australian Outback Psylocke and Dazzler, also Marrow, Monet, Magik (rumored coming) Wolfsbane, Cecelia Reyes, Syrin, Blink -I would buy all of these.
Avengers: Mockingbird, Crystal, Spectrum, Firestar, Sersi, Magdalene, Moondragon, Firebird..I'm sure others but that's all I've got right now.

And the villains. Oh the bad girls...Titania, Selene, Morgan Le Fay, Black Swan (a newer character but one that has stormed onto both toylines want list) Nebula, Deathbird, Sin, Moonstone, Hela, Superia, Enchantress, Typhoid Mary, Goblin Queen, Damask (yeah very minor character but I'd love to see that get made) Vertigo, Arclight, Crimson Cowl - probably others as well but that's a good number

And various Marvel characters: Misty Knight, Mary Jane Watson, Aurora, Guardian, Snowbird, Marina, Talisman, Dagger, Songbird, Angela, Silver Sable..

Now I know some of these are more minor characters that haven't a hope or prayer of getting made but just right there, that's getting close to 50 right there. And that's just the ones off the top of my head that I would be interested in purchasing. I'm sure other people would have their own additions.

The point to making this list just very quickly is there is a wealth of characters that could support a female-only subscription line for several years. While I don't have $2000 to throw down all at once if you spread that out over 2-3 years, it would definitely be doable for most die-hard collectors.

edit: yeah I added a few. But still mostly just off the top of my head.
