It should work with a M500.

You mean a M92 followed by a M500, don't you?
When you are saying more wheels, are you then thinking about multiple feeder wheels in line?
If so i think that would be a overly complex solution.
I do think that a solution with dual driven larger feeder wheels that drive the filament from both sides would be a much better solution than the one we use today tough.
A heatsink for the stepper motor could lower the temperature somewhat, the extreme would be forced cooling with a fan, but the stepper motor covers does not have space to do that, so you have to remove those.
Your suggestion of cool-down would require a quite time-consuming cycle, it would be something like this:
1.) retracting filament from the hotend
2.) turning off the heater
3.) turning off the stepper driver to the E axis
4.) waiting maybe 15mins (it is quite some mass to cool down)
5.) reheating the hotend
6.) turning on the stepper driver
7.) priming the nozzle
8.) resuming printing
This would add an impractical amount of time to your prints, so i do not think this is a way forward.
I still think that the best solution is to thermally separate the stepper motor axis from the feeder wheel.

Yes of cause, sorry
I am in the process of redrawing this prototype pictured in the first post in Autodesk Fusion 360 instead of Sketchup since i am trying to change over all my projects, and will probably have something ready to try in a few weeks (maybe sooner if i have the time), will then publish it on Youmagine and write in this thread.
