So I have been having another look at the Kharybdis and Dreadclaws and I've always felt their biggest problem is that they eat slots, namely valuable FA and HS ones.

But then I thought, with allies it is possible to run 4 HS and 4 FA slots. Would this perhaps be a viable list?

Main

Up top 3 Kharybdis:
2 Baledrakes
1 Dreadclaw:

Ally in up to
1 dread claw: With the allies troops choice inside
1 Kharybdis: With whatever you want inside

what would you go about including in this list?

Honestly this might be something I look into, I really like the idea, anyone have thoughts on the matter? What would you run? I'm ideally thinking 2 squads of 5 or so Nurgle combi terminators, and then 2 squads of plasma chosen with 2 squads of 14 CSM's with double plasma.
