Scenarios

Is there a way to script a scenario in which the following takes place:

After you reach control of 30 systems, civil warp erupts in your empire causing a third of your colonies to rebel, with the rebellion concentrating within a specific section of 10 star systems. In systems totally claimed by the rebels, two thirds of your ships/bases/units are controlled entirely by the rebels, forcing battles between your outnumbered forces, and the rebels'.

The rebels would be given a production bonus based on their planning, and they may even enlist the help of a few other empires who recognize their independence, and who also declare war on you to keep you busy on other fronts.

In systems where some of your colonies remain under your flag, only half the ships/bases/units are controlled by the rebels, leaving your empire to fight a stale war forcing you to send reinforcements to prevent your remaining colonies from being lost to the rebellion.

Then as you are about to win control over one of your disputed systems, the computer forces you to play as the remaining rebels (say you saw the light of the corruption of your own empire, and since the bearucrats won't listen to you, you have since decided to join the rebels who reluctantly make you their leader).

Is it possible? And since you are out to "liberate" your old empire, any glassing or destroying of planets or systems on your part would constitute an immediate loss of the game. You win by regaining control of your capital star system (at which point the all but 2 remaining systems will surrender to the "rebel" (your) empire leaving you to mop up the real instigators of the civil war... secret alien agents who control their hosts (and sport some pretty bad weapons when you attempt to wipe them out) - a nemesis for the whole galaxy.
