Alternate tf2 skins

Does anyone know how I could reskin the tf2 models so they are green instead of red blu but still keep the original skins intact?

I can imagine you could add a third skin to the blu and red ones for each model but gmod takes them from tf2 and i dont think i could do so in tf2 without a full recompile/replacement of originals.

Any ideas?

And who rated me dumb that’s not a dumb question.

edit the texture with vtfedit and some programs like photoshop, gimp, etc… no need to recompile something

Save yourself some time and just Hex these

shouldn’t be too hard for you to do
