An interesting idea, but Jason actually caring about MJ would be a little too complex for a superhero comic. Yes, sometimes Spider-Man feels like a soap opera that happens to have a superhero as the main character, and soap operas sometimes have "the other man" genuinely love the woman he is pursuing.
If Tom DeFalco was writing this story, he might have made Jason more complicated and not an egoist looking for a quick lay after a long chase.
