Peter Parker himself gets all the ladies. Since we have Peter Parker coming to the MCU
Bonnie Wright as Mary Jane
Bonnie Wright is hot. Like a supermodel. Like MJ should be. She also has good acting skills but wasn't given enough in Harry Potter. I feel she could lose the accent and Peters wife is Bonnie Wright.
Elle Fanning as Gwen Stacy
She has some very successful acting. I think she is on par with my second fan-cast of Gwen.
OR Annasophia Robb as Gwen Stacy
When I watched Soul Surfer, I saw Gwen Stacy. She is amazing for the role. She seemed very independent but supportive.
Felicity Jones as Felicia Hardy (Again, yes, she was well cast)
This girl is perfect. She already played her and was perfectly casted. She doesn't shy from action movies (eg The Amazing Spider-man 2, The Tempest and soon to be Rogue One which is amazing) and she can for sure do romance. She is also fresh off the Academy Awards guys, c'mon bring her back to the role.
Michelle Trachtenberg as Kitty Pryde
If they go for the Ultimate story, they would need Kitty Pryde eventually. I loved their relationship at first but then she got difficult. If Marvel got the rights back (which someday they will) then they would have to include Kitty. I feel that Michelle is a perfect fit for a younger Kitty, if they did is in the Fox universe then I'd be fine, but I want Kiter or Pryter if those shipments work.
Sarah Hyland as Betty Brant
I know she's a bit young, but they do date. She has a very snazzy personality on Modern Family but she is also very strong and independent in real life, just what every Parker girl is.
