wallacer:
Could these be used as CD? I’m not sure myself. Possibly with some greenstuffed beards…

With a headswap, sure, they’d be great!
Also some new weapons, for wysiwyg.
Ishkur Cinderhat:
Aye, without spears and with some nice curly GS beards, these would certainly look nice as Chaos Dwarfs!
Hashut’s Blessing:
Considering you’d have to change the weapons and, for an unstatufied look for them, a head swap too, it depends how much effort you can be bothered to put in. If you want CD sized stone golems, these could work though.
Uzkul Werit:
They’d be tastey for some Immortals, me thinks.
Loki:
I think just a beard would be enough to make them CD s 
and as Uzkul Werit says they would make a sweet unit of Immortals
GRNDL:
I think there is merit in these models. The head is easily painted as something metal, ie: as a mask, and some of their champ models already have a hat styled headgear. For those worried about weapon swaps, they do make a unit with hand weapons, including hammers, etc.

Still need beards and maybe mods to the feet.
Scion:
As already mentioned they’d make a great unit of Immortals, with that stone armour.
Zanko:
IMO with these heads some of these minis look like cool golems!
If you want to use them as a CD you IMO you should remove the complete head and use another one!
:hashut
AGPO:
Nah, they just don’t look right. Faces look too ‘orcy,’ the feet are wrong and they’re too lightly armoured. Better off going with normal Dwarfs IMO
Hrothgar Goldgreed:
Meh, I don´t like them enough. Rather give me some BfSPs to cut up, tomes down my anti-plastic hate feelings too 
The Brain:
With a headswap, sure, they'd be great!If you play by the Indy GT list regular CD can take spears.
Also some new weapons, for wysiwyg.
