Greg Hoffman did too good a job for me to want to ruin it.
Is it safe to use a Hot Gear bag to dry boots that have custom footbeds, and custom work done on the liner and shell?
It should not be a problem, though I did change the shape and support of some low temp plastic "stuff" when testing one of the early prototypes, before the temp limiter solved the issue. It was only the experimental materials I was using that was the problem.
Though I would check with Greg anyway.
