I don't think you should take any more advice on this - it's time to find out for yourself what you like.
I guess this is advice but,IMO, it's time for you to find out whether you like PG's or not, whether you like nickel covered PG's or uncovered PG's, and whether by using 300K pots you like throwing away highs forever and which you cannot ever recover by turning up the treble on your amp OR: whether you like keeping those highs by using 500K pots, which allows you to shape the tone, if need be, by turning down your guitar's tone control during the course of playing a song or solo. Once you throw away those highs they return to the planet Earth (AKA: "ground") never to be heard again - you can't recover them by turning up the treble on your amp because they won't exist anymore.
It's time for you to KNOW for yourself what this stuff sounds like - no one can tell you. You're just going round and round in circles from what I can see here.
Get this project out of the realm of thought and into the real world.
