I have been down this rabbit hole as well. For the longest time I needed everything to be the exact same or it really triggered me. This current year I have dropped my handicap by 4 and am playing some of the best golf I ever have. A few of my grips are different sizes, I have some unorthodox iron combos in my bag, now my mindset has gone from being uniform to now how can I replicate how this grip feels forever. If it works it works. Do not change.
