Its something I have done in the past.
I would imagine because of the small rotor diameter of low powered spindles then the large ER collet systems wont fit or be enough material left to safely adapt.
The cost to re-tool for an upgraded rotor for just a few specials wont be worth the expense in relation to demand.?

How did you fit a larger ER collet taper system into a smaller ER taper.?
