I'm not convinced you've thought this through properly. Beyond what geographic size, population count, and economic size does a state need to be split? And how do you know how many states it should be split into? I mean, Rome essentially split in half and ended up with two unmanageable nations. How do you know California doesn't need to be split into 3 or 4 states? Or for that matter, more states have more overhead (you need two legislatures, two cabinets, two of every cabinet position). How do you know the real solution isn't to combine California with Oregon and Washington?
