That's H-Bot, not CoreXY.

If you are trying to prevent the carriage from racking?, I don't think you have to worry about it (or do you?), as I believe that both the CoreXY, and H-Bot are inherently anti-racking linear motion systems. The driver (i.e. stepper motor) is the anchor of the anti-racking system.

This is more inline to your original idea.
The belts don't cross, and it's a simple design:

That one is made for pick-and--place type, if you implemented that on a gantry your motors would have to be mounted to an axis, removing the entire point of H-Bot.
Fabtotum's CoreXY mod is what I've found best. Simple and effective.
