I don't think Sharon will be second fiddle to Peggy, at least in terms of screentime.
Natasha is certainly the second main character in the movie, and much is made about her connection to Cap, so it's a safe bet that -baring some plot twists- she'll be the leading lady of future Cap movies as well.
