Bro, if u are still running SL5x5, where u squat on every session, i think it's ok if u wanna reduce it to 3x5 per session. Alternatively, u could go 5x5 every other session like i do, as i find squatting every session too taxing.
IMO, if there is more important body part(s), it is/ they are on the lower body. Getting a proportional body should be the goal, not Johnny Bravo
For your strength imbalance, unless u could no longer row properly, it shouldnt hinder u. If u are really concerned, go for dumb bells row meanwhile, so that your stronger side wont take over.
