Do you port the wastegates of the s5 turbos? If so how big? Can the back plate be milled for further WG travel?

I can port them a lot. I don't suggest a lot of porting if you are wanting to run 15 psi or more. The bigger the port, the more the boost wants to fall off at the top.
I can mill the cover for further extension if you want it. A rebuild and upgrade is all cleaned up and fully inspected before used. Only parts remanufactured in the center housing rotating assembly of the stage 2-3 is the shaft and the bearing housing. The rest is upgraded and replaced. The stage 4 the whole CHRA is new.
If you have broken bolts, I can handle removing them.
