The stakes getting even is one thing, your ideas are another which will NOT fulfill what you hope it will. What I’m saying is that you have shown explicitly that you don’t care about the Horde at all, and all of the characters you want to lead it will never even think about joining it. So your vision of the Horde will never come to pass.
But that’s ok, cause as I said - you don’t really care about the Horde, you just want to join a “strong” and “cool” faction. You think that the Alliance is both stronger and cooler than the Horde. If you have no attachment to the Horde whatsoever, which you don’t considering you’re willing to hand it over to complete monsters just so they can fit your vision of strength, then there’s nothing preventing you from joining the faction you think is superior in both those aspects.
Congratulations, Erevien. You’re part of the Alliance now.
