Changing Eyeball size improve circulation.

Regardless of how I aim my return jets, my pool wants to rotate clockwise. The only issue I have is the water moves too fast when moving clockwise and misses the skimmer at times. I don't have a variable speed pump. My pool pump is located near the top (see left image) which I believe makes the pool rotate clockwise since that is the closest jet and most powerful. All of my eyeball sizes are standard 3/4in. I am thinking I could add either a 3/8 or 1/2 eyeball to the top jet which should restrict the water there and slow down the water when rotating clockwise while increasing the power to the shallow end jet and lower jet which should take care of the dead area. Would this make sense without harming the piping or filter?

Smaller eyeballs = greater pressure out of that return. I switch to smaller ones when I run my pump on low a lot.
