I need to find a sealant for the threads as they will be exposed to gas, didn't really think that through. Any suggestions? I bought some Loctite No 567 sealant as it was recommended for gasoline.

He'd need about twice the thickness. I'm thinking that you start with twice the thickness, but mill out everything on the back side except for the screw bosses, leaving raised cylinders 2.5x the screw diameter to accept the threaded holes. That way the plate doesn't protrude from the end of the tank any more than it does now, but allows for blind holes. I'd leave a smooth radius around the bosses to reduce the chance of cracking. Just don't drill and tap too deeply into the bosses to keep the ends from fracturing, and mind how much threadlocker is put in there.
