Ended up sacrificing a treats piston port 45mm Version I piston. I didn't like relocating the ring pins on the treats reed kit piston and don't mind that the version I gap goes through the booster port. The port angle is gradual enough that it should never snag. Here come a ton of pictures:
Version I piston sits about 2mm below the top of the head surface (not counting a head gasket).
Intake side shots of the piston with an intake window marked out. Gives me 360* intake duration and compliments the shooter port well. Wanted to leave enough skirt below the window to keep the piston from cracking as well.
Drilled some holes in the piston to start with, then went to work with a couple files.
Finished intake window:
