batcave with every villain from the first lego batman game

Im mainly a Marvel collector and wanted to make my first dc diorama based on the first lego batman game because that roster is peak. The clayface is the only non-purist custom (besides a few handcuff methods). I want a bigger space for the batcave so i can have suit displays and not just the dinosaur but the coin and playing card too. I eventually want to get better parts for the mad hatter, ras al ghul, and killer crocs head from the arkham asylum set. Lemme know if you have any questions...
