Thicker plate is not as flexible.You can cut SS but I would think if you use a SS plate just getting a thicker plate would be easiest.
When I used to dive backmount I used a plate only with 15l, for 50% of the year for wetsuit fresh water diving, and then at first added 4kg for salt water, and then an additonal 1k for freshwater drysuit,
If I had a thicker plate, I'd be too negative 50% of my dives.
