My mounts have held up great - I've put a few thousand street miles and a couple track days (and canyon runs) on them, and it's just as stiff as the day I dropped the motor in. I can't see what could possibly go wrong, as long as the Window Weld (polyurethane) has a good bond to the rubber - wash/degrease them first, obviously. I'd definitely say it's got a better chance of holding up than a hockey puck with a hole in the middle.

There's no need for bolts through stock mounts, there are already correctly-offset bolts through the center for engine and crossmember, and any more bolts through the sides or whatever would just rip up the rubber and kill the damping of the mount.
