I think you are mistakenly thinking that if you've neglected something then you must work it harder by giving it a higher frequency.

This seems right when you think about it at first but really all you're going to do is overtrain at this point. I reccommend you hit the squats hard twice a week and deadlifts once. Base all your other exercises around hitting these two key lifts. Squats and deads are your lower body bread and butter.
