If a base fee in any lands, and the remainder or reversion in fee in the same lands, shall at the time of the passing of this Act, or at any time afterwards, be united in the same person, and at any time after the passing of this Act there shall be no intermediate estate between the base fee and the remainder or reversion, then and in such case the base fee shall not merge, but shall be ipso facto enlarged into as large an estate as the tenant in tail, with the consent of the protector, if any, might have created by any disposition under this Act, if such remainder or reversion had been vested in any other person.
