I think that maybe if you could prove you were making a movie and weren't just crazy that the agents might consider the project. I mean, low budgets and indie flicks get stars all the time. Send the agents a script, and if they think you're on the level, they'll pass it to Jennifer and she'll decide if she wants the part.
Unfortunately though, I would recommend you have a backup plan.
