Civ II offered the possibility to move your Palace (Capital) to another city for a certain price. A similar function in EU would be good but should have more pre-conditions than its Civ counterpart.
1) Moving your capital should be hugely expensive (2000 ducats?)
2) Only provinces with a certain(high) population should be able to accomadate a new capital
3) New capital should be as close as possible to old one
4) New capital must be on the same continent as the old one
5) Changing the seat of government immediately lowers your stability to -3 caused by the the administrative upheaval in your nation due to the move.
