I fit thick SA cogs on my Alfine 8. It takes about 15 minutes to sand down the excess thickness for them to fit. They don't need to be the precise thickness of Shimano ones.
Put 1m very coarse band-sander roll on a flat surface (I use an old shelf), rub the cog up and down until the indented text is barely visible. I made a plywood cog support this time and it speeds up the process.
