Recently a lot of newer and updated stadiums do some sort of light transformations when a homerun is hit by the home team. I know the Yankees, Braves, and Twins all have the newer LED lights at their stadiums and when a homerun is hit the lights flicker on and off.
I doubt this will be in the game this year but would be a cool addition. Not game changing however.
It’s a neat effect in real life, but I think it would just look weird in the game.
