As much as the work the guys on this site have released is fantastic, making modifications of an already completed game is not even in the same ballpark ( ) as creating a new game from scratch (See "Sandbox Games", thanks for the reminder of that abomination Y4L).
Like Y4L said, sell anything that even has a trace of EA attached to it would cause their lawyers to sue everyone here to the point that we'd be spending our days living in a cardboard box. And porting anything is not feasible without the source code, not to mention having to rewrite everything for it to execute on a linux-based OS, reducing file size/resource requirements to an insane level etc.
In short, no.
