I don't think so.

In normal Emacs, when the script finishes, it goes to the main input 
loop, which displays the buffer and processes terminal input. That's why 
it needs a terminal.

In batch mode, there's no terminal or redisplay, so there's no main 
input loop. It just runs the script and exits.

Running another process isn't compatible with this mode, because 
processing the process output is also part of that main input loop.
