You can mitigate the 'difficulty' of pedal pressure by changing the size and stroke of the MC's piston, which Chase Bays has figured out from hours upon hours of R&D. Supposedly they actually have some kind of proprietary design for the BMC that gives a much more even pedal feel over stock booster+mc setup.
That said, many opt to just swap in z32 Booster&MC with the cts 4/4 brembos, but I've only seen a couple mentions of that for the 6/4s. I'm assuming it's perfectly fine, and satisfactory for a non-racecar.
The main concern with really big brakes is locking them up, so to counteract that, you have to get really grippy tires, that only lock up in the last ~5-10% of pedal.
