NFL uniform question

There was more Alternate uniform flexibility back when the NFL allowed the use of alternate colored Helmets. (which there are rumors the 1 helmet restriction will be lifted in the 2021 season)

I feel like if they go back to allowing multiple Helmet colors, and increasing the Amount of games an Alternate uniform can be worn. I believe it's currently at 3 now. To maybe 5, or 6? You would see a lot more creativity with Throwbacks, and Alternate color set uniforms..
