Abin Suring him would be a huge mistake. I was just posting about this in the Avengers thread. I think the legacy aspect is the key to making this work.
You devote an entire film to Mar-Vell. Set it up so that he's in a relationship with Carol Danvers (doesn't have to be all that serious of one). Then he needs to sacrifice himself towards the end of the film, with a very heroic and noble death, probably saving the universe from something big. Ms Marvel gets her powers during this, and feels the need to pay homage to Mar-Vell, and not let his sacrifice end the legacy of a man she considers great. So she models herself after him, in "superhero name", costume, etc, trying to live up to his example. End it on her making that decision, on a hopeful note.
Or something along those lines.

You write a strong screenplay, assemble a strong cast, and just make the movie
