Merwyn already pointed out that replacement picks are cheap and weightless. Regarding the number of dice, every PF2 campaign I’ve been a part of (which is two, so a pretty small sample size) has just had the rogue roll for each tumbler right up front. Need 5 successes, roll 5 dice. If any of them are a critical success, it offsets a critical failure (in addition to counting for two tumblers as normal); otherwise, each critical failure = -1 replacement pick. It’s meant on average 2-3 sets of rolls per lock, rather than 7-8, and keeps things moving at a fine clip.
