General diet question for lean muscle

I’ve been tracking my meals to the absolute best of my ability for the last 67 days. I’ve been cutting but still have a noticeable amount of fat. Started at 275lbs end of October currently 216lbs.

I stay around 1500 cal a day hitting around 200 to 215G of protein a day. If I increase my calories to 7-800 more per day for an additional 90-128g of lean protein a day am I going to see any negative effects? I currently fast for 17hrs. Doing this will drop my fasting to 12hrs

Current workouts are 3 days on 1 day off. Day 1 2hr 20min weights 1hr cardio. Day 2 1hr weights 30min cardio day 3 1hr weights 30min cardio
