Looks like you've got a good plan going there. Agreed epoxy will add unwanted insulation to the NTC. I'd put a really thin layer over everything just to make sure nothing shorts out electrically. You can then make a bigger joint near the bottom for mechanical strength where the wires meet the board.
Thermistors are pretty tough, so I wouldn't worry too much about killing it with heat... Unless you really get it toasty.
