Keeping your options open is good for if you're not sure of what you want to do in future; and if you love those subjects, those subjects are great.
However, be cautious that Maths, English Lit and two Sciences may actually be more restrictive than you imagine, especially depending on what the two Sciences are. If you're aiming for A*A*A*A* with all 9s at GCSE, then I'm guessing you're aiming high. Without Further Maths, you may be less competitive for top Maths, Physics and Engineering degrees; without Chemistry and Biology, you may be less competitive for Medicine; and with only English, some Humanities degrees may also be less accessible. Four A-Levels can be quite a lot of work as well and take away from time that could be better spent elsewhere. It also requires a broad range of skills, which if you have them, is great, but may be more difficult.
That's not to say that this is a bad combination, not at all. Just some food for thought.
