Need material suggestion - Widening eye socket

So I need to widen the eye sockets on my first head (yes the foam and fur has enough give for me to achieve the size I want). I didnt think about the fur making the sockets look smaller and boy do they ever. My idea is to either use an epoxy to make the eyes stiff (though im afraid the head will melt the foamies) or more ideally, take something like an aluminum band/strap and shape it to teh size I want and insert it before inserting foamies.

Any suggestions?
