I ended up using feeler gauges with 600 grit sand paper (I made sure I used the proper gauge for each string, so that the gauge + the added thickness of the sand paper was spot on - I used a digital caliper for that). Very easy!!!
Turns out this is the easiest way of deepening/adjusting nut slots, without investing in expensive nut files.
You found your way to what I posted in the link above.

I don't go any finer than 220 as the process becomes too slow, and do the rough out work of first cutting the slot with a fine tooth hobby back saw.

After 45 years of cutting nut slots I've yet to purchase a specialty file for cutting slots. I do zero frets so often that I may not change my ways.
