This sounds sweet! Just the thing I've been waiting for I'll download and test right away, see if it does it for me. I thought the battles in NTW was a little meager when I've been spoiled with DarthMod in ETW. And I didn't want to increase the unit sizes myself in the preferences.script since there was no apparent way to scale-up the artillery along with it.
Cheers, and +rep!
EDIT: Although I think the NTW maps are a tad too small for so many units, but maybe it's a small price to pay ^^ at least I think the ETW maps feels bigger and more suitable for such large units.
