Enter the Dragon?

I admit to being a bit of a hypocrite with regards to the new Chaos Marine Heldrake and the other new daemon engines.  I don't think that they really fit in looks-wise with the other Chaos Marine stuff.  The Defiler, though crazy, was a much better fit aesthetically.  On their own they're OK, and if I had seen the Heldrake made by another company, like as a Warmachine Cryx monster, I would have been drooling over it wanting to find a way to use it as something counts-as in 40K.  

So I wouldn't want to bring a Heldrake or a Forgefiend into most regular CSM armies I would think of.  But might there be a way to use them nonetheless?  I think so.

They may not fit in well in my mind to a regular CSM force, but who might they fit in well with?

These guys.

I think that a flying mechanical dragon could fit in very nicely with the Scythiak.  With Allies, I could do it as an actual Heldrake instead of as a counts-as Valkyrie.

How might a Scythiak list look to bring in some CSM allies with a Heldrake?  I think that I can accomplish tying the CSM and the Heldrake separately in with the Scythiak.

So if I can get hold of a Heldrake for a reasonable price or as a present, might consider doing this.  I would also want to find a way to make a decent looking tail in place of the jet port rear end the regular kit has.

Not sure how I'd want to do up the CSM.  Regular Endless Ones, Sons of Taurus (coppery/bronze with black and silver), or a mixed hodge-podge of renegades.
