Would this be possible?

I just beat normal AI 2 v 2 on a medium sized map. I found I have a bunch of ships that I grew attached to. I was wondering if after you beat your enemies that some how the game continue.

The idea I was tossing around is that a worm hole opens qued by what would normally be the winning screen. When it opens a fairly large fleet would invade. If you could withstand the invasion go on the counter offensive to the new galaxy.

I do not know if any of that is impossible or not due to game limitations but I think it would be cool to be able to use some of the cap ships that I grew fond of.
