This is just an idea that popped into my head but since there are models for the Administrator, Ms. Pauline, the Civilian, the Director, and Saxton Hale (if you use the one off of the TF2 modded gamemode "TF2 vs Saxton Hale")

There is however no models for the Mann family, that is to say, Blutarch and Redmond, Zephaniah, or Grey Mann.

Just think of the possibilities of what could be made with them.
