Interesting suggestion! How well does epoxy take prolonged exposure to
moderate heat?

Anhydride cure epoxy will take 200 C continuous no problem. Ask
MasterBond, Devcon, Lord, Epo-Tek, or another major epoxy suppliers.
Pot life is an important consideration.

Ask a human rather than wade through the pdfs. Find an old fart who
has already made all of his mistakes.

sprinkle of cheap reasonably monodisperse solid glass microballs to
the goop to make the resistor's spacing automatic and idiot-resistant
throughout its large planar area.

I like the microballs idea .. makes perfect sense. But I wouldn't have
thought of it.

Thanks for your repsonse!
