Extras/Entourage mashup

I want to make a pilot or webseries or something that combines Extras and Entourage. It would be like, a Vinnie Chase guy who is an extra and really takes being an extra seriously, and he has to decide between being an extra in a Disney movie or Shutter Island. It's like Extras in that the main dude is an extra, but it's like Entourage in that he takes himelf very seriously.
