Here is a Daemons of Khorne team I recently built for Blood Bowl.
These are pretty much just straight Chaos Marauders. There are a few Empire/Bretonian heads and arms added for some variety. I also double downed on additional shoulder pads.
On the daemon half of the team, we have some standard weaponless Bloodletters, 2 of which have Heralds of Khorne heads.
The big Guy in the center is a Basic Heroquest Gargoyle standing in for a Bloodthirster. The Bloodthirster has had its wings replaced with Varghiest wings.
Lastly is an initial design for the team logo.
