Put it on the pile with all the other rumors. I wouldn't be opposed to the idea, but let's keep in mind that there have been rumors of:
Moon Knight (probably the most repeated rumor)
Daughters of the Dragon
Ghost Rider
Freakin' Spider-Man 2099 (yes, this was a rumor I saw)
I think I remember even seeing a Ms. Marvel Netflix rumor, although I may have been mixing that up with something else.
Unless there are signs that they'll produce more shows per year (which, frankly, isn't in Netflix's interests) or that some shows aren't getting second seasons, I don't think they can afford to do too many more.
