While it would be sick, it's not as easy as just adding another prop to the menu, since with that, you can easily utilize the code already built into the gamemode for changing into a prop:

Code:

if pl:Team() == TEAM_PROPS && pl:IsOnGround() && !pl:Crouching() && table.HasValue(USABLE_PROP_ENTITIES, ent:GetClass()) && ent:GetModel() then
        if table.HasValue(BANNED_PROP_MODELS, ent:GetModel()) then
            pl:ChatPrint("That prop has been banned by the server.")
        elseif ent:GetPhysicsObject():IsValid() && pl.ph_prop:GetModel() != ent:GetModel() then
             (do a bunch of shit)
        end

However, there's no way to reverse that, as in there's no built in function you can just call to turn you back into a tpose, and you would have to write your own. This isn't impossible of course, but lua kinda sucks and software development takes time and effort.

The closest alternative I can come up with is to add the corpse model that's on awesomebuilding, albeit that is significantly lamer.
