Iron Warriors Demons?

[Smurfs]

Yeah, I know that Iron Warriors dont use Demons. Buutttt.... If I just wanted the option for a squad or two of summoned lesser demons, what would you people suggest I use model wise? I was thinking if I ever wanted to do summoned demons for my Iron Warriors, I would want to make them robotic looking. Soo..... I was looking at the Epic line of models, and I came across the Eldar walkers (go look on gw's site). Does anyone know the scale for those at all?
Im looking forward to your suggestions!

I'd use the demons from the Fantasy Flight "Doom" boardgame:

Cyberdemon:

The Cyberdemon from the game itself would be relatively easy to convert from a Demon Prince model.

An alternative (and less obviously "demonic" version, might be something like this thing I built a few years ago, for my AdMech army:

Based on the boss fight "Voss" in Quake 4:

I can't really think of a cheap way of doing it, but I reckon blood letter, painted with mettallics (and quite possibly a few faded chevrons) would look absolutely bad a$$, expecially if you could replace some of the limbs with bionics.

Alternatively go down the Transforemers route; take the Iron Warriors' technology and bring it to life. I'd love to see a deamon infested wachine machine walking around and bringing hurt to the defenders of the Imperium and assorted xenos species :P

I'd combine necrons with bloodletters myself.

Face: bloodletter - horns
Neck/back: scarab
Torso: necron
Arms & legs: bloodletter with necron limbs as bionic parts
Weapon/hands: bloodletter

The IW are well known to use human conscripts/prisoners as meat shields/distractions.

No reason not to use inducted guard/zombies/flagellants /whatever.

As for robotic looking...servitors?

Cryx machine wraiths.

Thanks for the Ideas! Keep'em comin!

I think the Doom boardgame was the best suggestion - it was the first thing I thought of too before I even clicked.

Another suggestion could be to convert up Chaos Androids from necrons, skeletons and chaos bitz. Theres nothing to say they arent still in the backround, afterall.

Chaos Androids were basicly robots with Daemons bound to them afterall, which I think would suit the IW, right?

One suggestion a friend of mine had was to try and find some old school Necron Immortals and just use them. Thoughts?
