Good news! I think Bucky is great (in general, but also yours in particular) and will happily throw ladies at him. Wanda and Bucky are a favorite, obviously, but I'm down for whatever else you fancy.

Peggy? Hell yeah.

Kara? Oh, you mean Bucky with an unhappy ending? Let's give her a happier one.

Misty? They can be robot arm friends.

Darcy? Darcy goes well with everyone.

Seriously, just lmk what you're interested in. I'd play romance/etc. with Bucky with, let's see, Wanda, Peggy, Jemma, Bobbi, Helen, Karen, Trish, Misty, Darcy; gen is very open with everyone.
