You can't change the AI present in the map without altering the spawn points in the actual raw map file and recompile it.
As the raw .ed file for the map you describe hasn't been released, you won't be able to do so.
I could do it myself sometime and re-release the map but my workload at the moment is a little prohibitive. Maybe later. No promises. Nonetheless, I still have at least one more old map I want to tidy up and release - just haven't gotten around to it just yet.
