Just because it's a bad idea is really no reason not to try it. That's how people learn without the luxury of internet forums.

This kind of reminds me of the time I tried to make a 54cm frame fit me when I need a 60 cm. It involved a long stem and a pair of hi rise bmx bars installed horizontally. It was so stupid. However it did force me to think for myself and ride a whole season where the easiest 'right' choice would have been to get a proper frame, which involved no personal creativity and cost money.

So anyway, there's more than one way to do things. I'd rather hear from someone who was running fixed gear and complaining about not being able to coast or shift and actually tried to do something about it, rather than someone who was told it was impossible and accepted it and gave up.
