Another Doctor Who idea... as the Emperor falls down the DS2 core the footage starts to rotate and it fades into the spinning Dr Who time vortex and music.
Also cut in the post credits 'Masters of the universe' scene just after Palpatine hits the bottom (But with Ian McDiarmid dubbed over Frank Langella)...

obviosuly you'd need to do a quick colour correct to turn the shot from pink to blue.
