Structuring Dissertation as Thesis Rather than "Standard" Bachelor's Structure
LaTex is irrelevant for the question. But there is no reason not to do it your way provided that there aren't rules that prevent it. But your advisor is the best guide here. 

In fact, since you intend to move to doctoral studies the experience would probably be worth any additional effort. 

But you need to get some assurance that you won't get late push-back on it from anyone. Again, your advisor, or other faculty should be able to give the best advice.
