OK, I figured I'd at least get the ball rolling on a workshop for these guys.
Here are the Characters from Fourth World I’m interested in:
Apokolips
Darkseid
Desaad
Kalibak
Grayven
Steppenwolf
Granny Goodness
Female Furies (Bernadeth, Lashina, Mad Harriet,
Stompa, Knockout)
New Gods
Highfather
Orion
Metron
Lightray
Big Barda
Mister Miracle
Of these we have a Darkseid (I), his Parademon armies, and Knockout.
There are plans in the sanctum for Big Barda and Mister Miracle.
This leaves a ton of room for operation.
I'd love to see the Apokolips troops work to synergize with Darkseid and the Parademons and tie them together into a nasty faction that brings Darkseid back to relevance.
I'd love to see the Female Furies and Granny Goodness have some synergy.
I'd love to see the New Gods work well independently but possibly boost each other as well. Metron should be a really solid support figure, IMO, and Orion should be Silver Surfer-like in power.
I've got some write ups for a few of these (Orion and Lightray in particular) that I can post if there's interest.
I'll try to update the OP with links to workshopped ideas.
