Nah too expensive try these people or go to your local bearing supplier as they are often cheaper and will sell without Vat for cash.

Your gantry is looking slightly better but still needs work. Also by the looks of it you haven't given much thought to how the ballscrew end bearings will mount and how the motor will connect.? Has it stands now it can't be done without special machining and using FF/FK bearing blocks.

10mm plate would be better for the bearing plate 6mm is still a bit flimsy.! Can't afford any flex or resonance here.
