Couple pages back we were talking about this because James Gunn said that the comic character's father is NOT (J'son or whoever-it-is-now after Star-Lord's origin retcons) the same as the MCU character's father.
Honestly, Star-Fox has the best odds in my opinion. The MCU Peter Quill's personality matches Star-Fox's personality to a 'T'...mainly due to his womanizing and crazy "Eternal" playboy antics. Plus, it gives Eternal blood to Quill and "explains" how he can handle the power of an Infinity Gem. It also makes the "quest" for the Guardians that much more personal since Thanos would be Quill's uncle.
Okay, I confused Star-Fox with Starhawk my bad. Eros (Star-Fox) is a much better choice who I hadn't thought of...maybe the we'll be seeing him soon comment from gunn refers to a scene from Thanos' past.
