First of all, thanks for the positive imput.
I like the whole pet idea a lot, especially since that's not exactly what I had in mind when I posted this. I was just thinking it would be interesting to sort of see the whole of Cradle at war, and having missions to accept from Spiral HQ, like defending the Ironclaw Munitions Factory alongside gremlins or the Lower Gardens alongside wolvers, and maybe a few witty dialogues with some of the more well-known former enemies, like Vanaduke.
But I rather think the pet thing is easier to put into practice, and it would save you the trouble of having to revive rather useless mecha knights that have a tendency of doing more damage to you than to the enemy.
Oh and since I'm already on a roll I should just mention I was baffeled to see there were no sleep-alligned weapons at all, and those rare Zee Cores you get from Slumbargos(at least that's what I think they're called) are absolutely useless. Just saying.

My mistake.They're called Slooms and Sloombargos, are apparently very rare, and the misterious Zee Core they drop really is plain useless for the moment(just checked with the Wiki). A sleep alligned weapons line that uses Zee Cores for crafting would have to be really tough though, but again, I'd rather not fill up the forums with my half-baked ideas unless someone seems interested. Anyway, thanks again for your comments.
