Ahh, I misunderstood what you were trying to do.  I can't think of any
way to do that with the builtin code.  You need something to setup a
PythonInterpreter and to tell it what file to run.  That code would be
really simple though, so you could generate that source as part of
your maven plugin.

To remove the need to set things up like that, we could add a main
method to the class files we make for .py files.  That could handle
making an interpreter and then telling it what to execute.  I'll see
if we can do something like that.
