There are bounds on the entropy that can be contained in any given region, but I’m not sure whether the reason we believe these bounds to hold implicitly assumes no basement universes exist. Does anyone know?
In the linked comments, Mitchell Porter points out you’d need an infinite amount of stuff to throw into the basement universe, though for all I know whatever technology allowed you to create basement universes in the first place would let you solve this also.
