If you even played the said meta you'd realize this wouldn't change shit but bump no more than twelve Pokémon up a grade or so. You're not gonna copy a 600 BST in OU, so the stats you're gaining most likely would not amount to much without extra boosts to go with the gains. This sounds like the Duel Skills from Fire Emblem Heroes, addressing the power creep by putting a band-aid on a severed leg. These did not shift the meta in the slightest because everyone who would get big stat gains have dogshit weapons, to the point where the only appeal is novelty.
