You are correct in that moving the Forbidden Palace is impossible.
Moving the palace moves one of your (potenetially) 2 cores of production and commerce. If you move it to somewhere else it is a good idea to build courthouses in all your old palace-core cities, so that they may sill produce a few shields (even with 95% corruption, which is the maximum corruption).
The impact of moving the palace on culture is minimal (<1000 points). This is because you only miss the 'doubling' effect for 1000 years, and even at 1 turn per year that is a maximum 1000 culture points. (Note the real 'max' amount of culture you can lose is somewhat less than this due to turn lengths, unless you mod the game to last beyond 2050 or mod the year-turns).
