Well, after some head scratching and pondering, I remembered to check an older "archived" DVD of UltraHal related files: skins, textures, characters, backgrounds, brains...yeah...that was the one.
Sure enough, BlankSlateBrain.uhp (or something similar).
Downside...Like I mentioned, it was for Hal 5.X not 6.X
If one wishes to use it in hopes of possibly modifying it then feel free but do not expect it to work with Hal 6.X as the old one used .brn files and not the Tables.
Proceed at your own risk, and by all means read the Instructions at the top of the file once opened (use text editor) - Likewise if someone else has a version for 6.X then by all means post away!
Here ya go:
