I actually read the posts here before the PM, and I really don't mind you beefing it up. I've been meaning to high-polify it anyway, so you're saving me the work. The other people involved in its creation were CODEDOG NG as you've mentioned, Mikhael, and Lt. Narol (those guys work on the 158th). The point of the mod, though, was a public WIP, where everyone who wanted to could have a hand in working on it, so you are perfectly welcome to finish your model.
The only thing that I would ask that you adhere to the original spirit of the mod and make it a public release. If you're dead-set against it then I'm not going to stop you from using what you have however you'd like, but I'd like it public if that's at all possible.
