roslaunch might add extra parameters like __name and __log. The non-ros executable should be able to handle those (by ignoring)
Another possibility would be to write a little wrapper program that calls whatever program you'd like; by using the ros init stuff, it could parse out the roslaunch arguments, and do what you want.
The aliencontrol ROS package is a generic wrapper that can launch any external script or executable. You might want to give it a try.
