Yes, I have played against Guild and against Lady Justice quite a few times now with Nidoderm and Seamus and have been able to win and playing the "cuddled" rules from the get go.
It's still fine. The Guild would still be able to rid you of your zombies because zombies count as corpses. They can just say, "Zombies be gone."
With Nicoderm you get "Bolster Undead" which is WAY better than bringing in Zombies when fighting the Death Marshals. Df 7, Cb 9:malicrows with 2/4/5 Dg, Rot, flurry, Slow to Die is some pretty damn hard hitting Zombie Punks. And the fact that Nicoderm has Fog, you can basicaly just forget the Zombies with them and just go for their throats.
Imagine bringing in Killjoy in this list at 30ss and letting Mortimer sit home and dig by himself.
This is not a cuddle unless all you care about is having Zombies at all times, but I've done quite well without them.
