Excellent idea, the following are non-resetable but go a little higher to 240C trip temp (not max operating temp which some searches provide)Quote

I did some research on thermal fuses, however the highest holding temperature I found was 200C. This is a little too low even for PLA printing.

I found by thermistor a very tight fit in the block, but can see the heat shrink idea is good and I could also benefit from securing the connectors.Quote

The first thing that springs to mind is a more precise way to secure the thermistor in the block. I secured mine by bending the leads around the block, but its not very satisfactory.
One option is to get some larger diameter heatshrink ( or something ) to act as a stop and put that on one lead so you can slide the thermistor in from one end to a known point. Then add clamps ( e.g screw terminals) somewhere to secure the other end. (EDIT: Both ends!) Maybe the bit of paxolin above the block could be extended to mount clamps on.

These are AC current rated and I haven't investigated there DC performance (often a lower rating due to arcing)
