Hey Gadrick - I did - or more accurately, I did partially. I needed to work on my extruder, and ended up pulling the x--carriage off - so I replaced the pulley and popped on the GT2's.
I was not able to measure any appreciable difference between the MXL's and the GT2's. I'm sure that under higher speed / higher load there may be a measurable difference, but I didn't see it. I also didn't really push the jerk or acceleration much higher to test, as regardless of the belt type I was running into mechanical vibrations / ringing that was not related to the belts.
So - no -
Save the pulleys for something else.

Did you ever do this testing? I've got GT2 pulleys sitting here and was wondering if it was worth while to order some belt and switch over.
