Add ProStandard to Fujifilm ICC?

 Will a dedicated Fujifilm ProStandard ICC be another level up or is the ProStandard your new generic?
In not being satisfied with the Fujifilm generic ICC profile, I started trialling many of your other manufacturers' ProStandard base ICCs. I settled on something I didn't expect; Using the Sony A1 ProStandard ICC as my Fujifilm camera default with the Film Standard curve. This ProStandard ICC still works well for me with Fujifilm's own film profiles, including the new Nostalgic Neg, and yes they are altered too.
