Really nice attempt! Makes me want to try some panoramas too. One thing about your idea though, if you use a CPL during panoramic shooting you will likely run into trouble - the CPL effect depends a lot of the shooting direction and if you use it in a panorma, you will likely see big differences in sky color etc.

By the way, I've also considered the cheap option for the macro tripod ring - what's the "brand" of yours?
