Help needed for CMORising some ACCESS-OM2 output

I’ve been building transport matrices from ACCESS-ESM1.5 CMIP6 output, and I’d like to use the same code to do the same but from ACCESS-OM2. For this I’d like the ACCESS-OM2 output to be in the same format as what can be found in CMIP6, as this could avoid me some headaches. For example, I’d like to avoid re-building the cell vertices myself by hand (variables vertices_latitude and vertices_longitude). Can I do that by CMORising ACCESS-OM2 output? If yes, should I use ACCESS-MOPPeR? Note that I’m only looking for a tiny fraction of the output (just a few variables, and over just a year or a decade at this stage), so nothing expensive in compute resources. Any guidance much appreciated!
