Hi there,
As long as your A-levels meet the requirements of the universities you apply for i.e., are relevant subjects and grade boundaries, then you will not be disadvantaged! As far as I'm aware your A-level choices meet any course requirements for a law degree so I wouldn't worry about having to drop or change it unless there is something else you would really like to do instead.
Universities are looking for students who are interested and dedicated to the course. Your choices of A-levels wont hold you back and as long as you put your best work in for the grade requirements you'll be fine! If you want to boost your application, I would recommend doing some reading or getting some experience to have something to talk about in your personal statement and interview and boost your personal development.
Good luck,
