Another options is to 'tuck' the fan leaves so they don't block anything.
I try not to remove anything unless it is hurting something.
Most don't remove vegetation until close til the end. How far along are you?
Some remove lower growth & popcorn buds to allow plant to focus energy on main colas. Other remove lower vegetation to improve circulation.
I did not remove anything during my last grow. Air flow was fine, I tucked some leaves out of the way, a number of leaves ended up yellowing & dropping off, etc.
