Goal of the realm would be to hold a single region as capital, and raid/plunder for anything it needs. Surely at least one realm would like to ally such a band of misfits 
If such a thing is, in fact, possible, then it shouldn't be.
I think Lapallanch was among those interested in creating a much less stereotypical "evil" realm a couple of years ago—one that would attempt to be publicly polite and friendly, while actually committing all kinds of nasty acts.
That seems like a much more interesting kind of evil to me. Yours just sounds like playing chicken with the game.
