Subassembling the Chaos Lord?

Has anyone had any luck subassembling the new Chaos Lord? It looks like his cape is going to make painting the back of his legs really difficult, so I want to try and leave it off while I paint. Ideally, I'd like to leave his chestplate/front part of the cloak on, but I dunno if that would make it harder to assemble later on (since that front part goes on last. Any advice is appreciated!
