If, in the process of pulling the panel and replacing it with a larger
200 amp panel gives you access to wire runs, you should at a minimum
run romex to a point that would facilitate the new rooms. Even if you
just leave it coiled in the attic or basement depending on your
situation.

It is very easy to come back and add circuit breakers later on and tie
them in. The difficult part is in running the romex.
