Anatomy of the engine mount

With uprated engine torque, I have a problem with engine movement. So it is time to think about some uprated engine mounts. There are few options, some more, some less expensive, but I would like to figure out some proprietary construction of my own ;).
First analysis needs to be done of what we have stock. I have taken old and teared away hydraulic engine mount:Cut top of it, to see what is inside. Quite complicated internals:Dismantled middle part:Nice pot to fill it with something (nylon? polyurethane?). Will think about it:
Burned remaining rubber with propane torch, however no pictures. It is interesting what would happen if to fill this area with polyester epoxy and glass fiber. Will it crack? We will see ;).
