Leg Day

I’ve been dinosaur training lately, and I was setting up workouts for the next 6 weeks, and I was hoping for some opinions. Would hitting a 20 rep squat workout (12 RM) and heavy box squats (4 X 3)be too much recovery wise for one workout, even with 3 days scheduled in of rest after this workout. If so, which would you recommend to hit first, I’m thinking if not both now, one this training cycle, one next. Any help would be appreciated.
