I doubt it would've made much of a difference. IIRC, PS4 components were much easier to come by than PS5 components. That's also why it was so easy to find an Xbox Series S throughout 2021 over a Series X because the Series S uses much easier to obtain components.
Sony most likely saw demand was stupid high for the PS5 that they decided making too many PS4's wasn't worth it.
