It would make absolutely zero difference outside of increasing your load times sometimes, & adding hours to your matchmaking. To enhance the entire game it would need rebuilding, cost a fortune & it's a very dated looking game as is, it would improve much. The game is literally dying & they're desperate for every penny, to the state where the new dlc is barren & you're expecting a whole game rebuild whilst also cutting off half the already very low income stream (yes Sony said last month 50% of their active players are still on PS4). In another world we'd be due a new game now, & it would be current gen only, but it's not & we're not.
