Consider a macro-reversing adapter. It screws into the filter threads and let you mount the lens backward, you don't get metering or AF or anything like that, and I hear you need a LOT of light, but you'll get good shots I think.
You know, I could tell you that this is a beautiful photo and the colors are amazing, but everyone has already said that. Anyway, the reason I like this photo is because it's just...cool. Like the wearing sunglasses, sauntering down the hall, breaking the rules just because, kind of cool. That's the best way I could describe it. Well done!
