This should help you with creating your own LUTs:

You can also create transformation LUTs from Slog to Slog2 or 3 if you prefer, but I don't think it's necessary. I would suggest to transform your color space from original S-Gamut to S-Gamut 3.cine and then do a REC709 conversion, because original S-Gamut has a pretty bad color.
It's funny when people suggest to work in ACES without knowing what ACES actually is.
