There is no way you cam change props in Prop Hunt TF2.
Technically, no, not officially. There are skins that you can download to change the Rocket Launcher and/or the Greande Launcher.
Custom skins only appear to you, and do not travel over the network, unless you have used a hacking program which does so. Sites such as FPSBanana hold skins which, to my knowledge, are perfectly safe. It is perfectly legal to utilize custom skins over online systems. They will only appear to you, and no one else will ever know.
You either buy them from the TF2 catalog or you get them in random drops. So far there haven't been any way to get them for free, aside from trading and finding them.
