Glutos Orscollion from AoS

[Valkyrion]

I've found a sealed box of this big dude and was going to put it in my spring ebay pile, but I've done a bit of googling and noticed that it's really a platform being pulled by a couple of daemon brute things. The parasol is a little out place, but I think I can 40k it up by using some EC logos, chaos stars and the like, and replacing the AoS characters with EC/CSM, except that big dude at the back which I'm at a bit of a loss with. Could paint it up as a statue, maybe? 

I don't know what I'd use it as - defiler or soulgrinder probably - but it's more about the modelling of it.

 

So if anyone has any thoughts I'd be very interested to hear. Maybe the whole aesthetic is just too AoS and not as 40k-able as I think.
