No matter who you decide to be I will love you forever!!!
I've cosplayed Otacon a couple of times. Wonderful cosplay in that I can use my own hair, my own glasses, and his clothes are really comfy! (MGS2)
Unfortunately, my hair has grown out now over my face and I am not really wanting to cut it up again. If I can find a wig that looks akin to his hair I will TOTALLY be there in 2010. Heck, I wanted to cosplay him THIS year but, like I said before, don't want to cut my hair. XD
Seriously dude, you rock.
