Thanks folks, this has been really helpful!
My plan is to have a circular base with a wall running down the middle. Both sides of the wall will be set up identically with some of the lab equipment referenced above. On one side I plan to have Ironclad's Doctor Jekyll while on the other Seamus, Avatar of Doom - before and after, so to speak.
Given how fast I paint there is a good chance I'll be celebrating New Year's Day 2016 when I lay down my brushes!
