That looks like a solid machine. My only thoughts are
1) if possible don't cantilever your hotend from the rail in that way, consider instead using 2 rails in a horizontal pair for your x-axis and placing the hot end between them. If I change my corexy this would be one thing I would do. Your using metal x carriage and hotend clamp so the nozzle movement should be small but its a good principle and you could start off with this (which is optimum) at this stage. The only drawback is increased moving mass, but the accuracy improvement is probably worth the speed reduction.
2) the v-wheels and leadscrews should give a decent z axis. Consider driving them both from 1 motor (possibly with gearing - gearbox or pulleys/belts if it needs it).
Yes, the wheels will be placed on an excentric spacer and mounted on a 6mm aluminum plate. I plan to let the wheels run along the white aluminum profile on each side, and they will lead the bottom white profile in the z-axis. It will thereby only be able to move, along the z-axis.Quote

Will the Vee wheels be on excentric spacers?
I can't see how wheels and grooves will be used on Z axis,
and where leadscrews will be
Remember bed should be restricted to only move in Z,
with bed parallel to X Y plane.

Which side is the front? You might have issues with access with the current setup.
