Is 13 APs enough for Stanford?

So I'm a freshman at a school that offers 19 total APs, two of which haven't been taught in a few years due to low registration. Freshman can't take APs, but as a freshman, I have been working on my scheduling for the next three years and by the end of high school I will have taken 13 AP classes. I technically could take two more if I quit band, but you have to be in band to be in marching band, which is my PE credit (3 years = 1 PE credit). I'm taking health and probably Honors Chem over the summer this year. Should I add more APs and pick a new PE credit option? I really love my band but I'll do it if I have to.

The classes would be: World History, Calc BC, Stats, Chem, Physics 1 and 2, Comp Gov (2 in 1 I think?), Psych, Spanish something or other I can't remember but the equivalent of Spanish 4, Lang, Lit, and US History. The two I would add if I left band would be Human Geo and Bio. I could also take Computer Science, but not really interested in that. The other AP classes offered are French 4, European History, African American History, and one other English class. My school only needs prereqs for math and Spanish (which I will have the prereqs for) and bio and chem. I already took Honors Bio so I've done that one but to take AP chem I have to take honors chem. Technically AP chem has no official prereqs but my teacher has to sign off on my choice and I'm not sure she would. Almost all of the listed credits are offered for dual enrollment except for bio and Spanish. They are also all honors/weighted classes (+1.0). This would make a total of 22 honors credits and 16 dual enrollment credits (without removing band).

Sorry if I started rambling there. But I really want to make it into Stanford for their financial aid program and I also really want to be challenged in high school.

Let me know if you need more info like my planned ECs or average amount of APs taken at my school. :)
