You may need a better insulator than PTFE; makergear offers PEEK that
apparently has better qualities at higher temperatures. The motor should
be OK, the temperature seldom travels that high. If you wanted, you
could make the insulator column longer just in case.
Use a minimal diameter of plastic filament to improve extrusion
characteristics. There's a shift away from 3mm filaments in the 3D
printing community towards far smaller sizes for this reason.
I don't know about the nichrome. I do know that a significant increase
in temperature may affect the glue on kapton tape.
