English is generally not seen as sequential as math or foreign language. Colleges may be less likely to see completion of AP English as one’s third English course as equivalent of “four years” of English, compared to seeing foreign language level 4 or AP level as equivalent to “four years” of foreign language. So the OP may need to take some English course for a fourth year.
While there are 5 AP courses listed for the proposed senior year schedule, all of them are generally considered lighter ones, since they typically cover over a year in high school the material found in a semester or less of college course work. While I agree that there is no reason to try to run up the count of AP courses, particularly with the lighter ones, the fact that they are lighter ones means that the OP should not be afraid of taking any or even all of them as academic electives if s/he is truly interested in their subject matter.
