I've done similar on old Kawas. One or two words of warning (nobody asked for):

1) You either want floating calipers and a rigid disk or a rigid caliper and floating disks. The setup shown, will have a stupidly hard bite and not brake even remotely as good as it could.
2) The stock calipers (freshly overhauled with new seals and pistons), together with a 14mm master cylinder and braided brake hose allowed me during some riding instructor-tests to be among the top third of in brake performance, only really had to give in to a guy with a 2021 KTM, 4 pots and ABS, who cheated and didn't turn his braking aids off. In comparison to all the others I was a bit less consistent, but my best brake performances matched some of their more average ones.
3) There's floating disks available from EBC, they are expensive, but worth every penny.
4) EBC and some others make proper race compound pads. They eat brake disks alive and you have to get them up to temp by braking once or twice. Then falling not falling on your face with your bike will be the next challenge.

Hope this gives you some ideas - clears out some misconceptions.

Cheers,
Greg
