Oceanic Cube 30 to Rimless Mod?

Have an Oceanic 30 gal. (around 20 in. cube) that has developed a slow leak around tank top. Water & salt creep around top back & down outside one corner). Currently using as 2/3 full QT with no problems.

After moving QT fish out to DT, my options are to repair by removing all inside silicone (including top lip) and re-silicone tank or maybe converting to rimless as a learning project. How tall a rimless could I safely go with a glass thickness of 5/16 in. ? If doable, would have the glass cut locally and build tank myself.

Did some searching and found an Excel spreadsheet glass thickness calculator online. Still, need to know what is the required safety factor for a rimless tank. Anyone knows it or can point where to find it? Thank you!
