As a side note to this thread, please consider the following. Calfiornia could have gotten away with requiring a waiting period for guns before the 14th Amendment (14A) was ratified. This is because the Founding States had decided not to make the rights protected by the BoR, including 2A, applicable to the states. Again, 14A changed that.
It might have. There were state court rulings that said that the second amendment applied to the states before California became a state.
