I meant to suggest the GEP Gun on the custom weapons thread that we don't have. Anyway, I'll stay on topic with the thread and suggest a JC Denton playermodel as well:
The protagonist of Deus Ex. Funnily enough, he's more suited to be a Spy model replacer since he's so slim. Here are some links for a Gmod playermodel and ragdoll, respectively, depending on what you'd need. Shouldn't be hard to port him over to TF2:
The only reason to add it would be to get loadsamoney because i can already see kids donating just to be this horrible fetish-filled monstrosity of a model, and for other users that exact same fetish i wont call out staff members.
Not only that but female models seem to attract an extremely cancerous community from what i've seen (Glubbable's server is an example, then again they mixed that same community with the FNAF kids, and green's server isn't popular enough for that to happen.)
I do know you want it for no particular reason, but you're a vocal minority, truth is most people would want it because boobs, and if we obeyed users just by "i want it because i like it" we'd have 40 different models from different animes/cancerous fanbases (homestuck) and the server would be a clusterfuck. I'd rather have more special and iconic models that can be neutrally good and not considered good just by someone's fetish. Doomguy, Mario, Luigi, Sonic are examples of neutrally good, special, iconic models that everyone could like. Fempyro, Femscout, Obscure Character from Obscure Game are examples of characters only a very small group of people would like, or in the case of the female models only horny teenage boys would like, hell we could even slap a O.W.N logo and red hair on the femscout to rake in more money.
This would be the start of a series of horrible steps into the server's doom, starting with titty-monster pyro, passing by O.W.N OC's, and finishing off with annoying MLP/anime models.
