Going back to your original question, based on everything you explained so far, while I don’t know if 6 AP’s are a good idea or why would you want it, I don’t think 6 AP’s while preparing for additional standardized test would be too much for your son. He may well find some time to read some novels, spend time with family and friend and do enough exercise too.
Apples and pears. But during last year, 13 yo my homeschooling daughter completed 9 courses 32 community college units 5 courses with lab, studied for SSAT test and took it, applied to a dozen boarding schools with visiting them, writing essays, etc, had 4 hours per week rock climbing team practices with joining a few competitions, self-studying geometry and algebra II in addition to college courses, participated local teen’s night hangouts, read dozens of novels outside of classes, visited museums, followed the election, applied to art competitions and juried shows, won regional kids competitions and was selected and exhibited on juried shows for adult artists and was still physically and emotionally fine.
It wasn’t easy. she constantly burned midnight oils, was getting very tired near end of the Spring semester, and even got a B on her Physics (equiv AP Physics 1) But she managed, learned a tone of academic materials, and most importantly, learned endurance and resilience by working real hard, as hard as it takes.
She also learned how to manage schedule, stress, anxiety and mood swings by always squeezing time for for exercise and joining regular teen nights, unless she is not prepared for Physics exam the next day, how to prioritize and where to focus and what to give up, where to let it slip, how to talk to professors and resolve schedule conflict and get special arrangements when needed, how to quantitatively calculating risks (I thought her this skill) and boldly taking them, etc etc.
So do I think your smart, dedicated, hard working rising junior should be allowed to take 6 AP courses that he wants to take? My answer is that only you really know. But my guess is probably yes.
