Interesting idea on the bearings, hadn’t heard of that.
It used to be kinda cheap when I started spec racing. But these days motors and ESCs have raised in price to get you the lowest resistance or smoothest throttle. Some guys are paying nearly $400 for Orion's HMX stock ESC just as an example.
But the bearings are a cheap method if you have time to kill

just open the seals degrease the bearings and then use some bearing oil on them. Should be buttery smooth. Just not as light as ceramic.
