I don't know how brittle the plastic is, is it like egg shell fragile or is it durable enough to make a mold?, maybe you could reinforce the back with fiberglass resin and mat and then seal the front with a couple of coats of satin clear to make it sturdier.
there is a few products available for life casting, Smooth-on makes a product called Body Double that is silicone based, that's easy to work with and looks very easy to demold, there are several tutorials on you tube about it.
if it's gentle enough for human skin, it should work for the clown face, I don't know, just throwing the idea out there.
