I'll probably build a Conan vs the world display.
Just take a long shelf and place the Conan Rage of the Undying facing the ARH Minotaurus and Oglavaeil, they are the two 'tanks'.
Behind them, the Siren, lurking. I could make a hole in the shelf where the Siren emerges from the water, her tail would go down on the lower shelf.
At the Siren's side, Kier the Valkyrie as a bodyguard.
Behind them, Xiall as the back-line sorcerer and behind her, on a riser, Morthigull, end level boss
I'd also tape the back panel of the shelf with a big fantasy poster/print with a cathacomb/undead theme.
That's more or less my wet dream.
