The magnetic forces on the coils are not that high except during a sudden short ( braking).
As long as your resin doesn't go soft you should be ok. Perhaps some measurement of hardness as you heat it would be a guide. All resins soften with heat, normal epoxy is virtually useless above 100C. Polyester is not really rated for high temperatures but short term it seems to hold reasonably well to about 140C. Vinyl is supposed to be better. Special epoxies can survive 250C in VPI motor windings but I don't know how soft they are ( core slots hold coils).
Bear in mind that the failures you see here have burnt copper and that is with wire rated for 200C service so you can guess the temperature they have reached.
I also have reservations about sticking coils together with super glue, I have no idea of temperature rating of cyanoacrolate bur I suspect it is just a messy contaminant at 200C and will be pushing the coil apart. These are the sort of things you could find out in your life tests.
In the end you can't run electrical machines at 40% efficiency and expect huge ratings unless you do something drastically different from normal construction. Best keep to a sensible rating or adopt mppt and get efficiency up to 70% plus then this burn out worry mainly goes away.
