Nice prices on those bearings. I get mine from VXB.
If you are just wanting a high speed spindle, why bother with the X2 head. Just use the China product instead.
You will surely loose torque at any lower speeds with the setup you mention.
Mine is not bad with a 2HP DC motor. My slow speed is about 1000 and high speed is 6600 rpm. This is without a belt change. When I run really slow like that using an 1.25" face mill, it will stall if I take to deep a pass in steel. I generally run it at 2000 instead. I run my other steel parts at 3000 rpm taking off only .02" DOC. The parts are mounted on a magnetic chuck and much more would loose hold on the chuck.
When I cut steel in a vise, I slow it down and cut deeper per pass. With any aluminum, my speed is always 6600 RPM.
I think this is all a very good range for an X2 head. Pretty versatile really. The entire setup including motor controller and speed control board was less than $300.
Just curious about the reason behind the spindle you are suggesting. Maybe something I am missing?
