side pull u-brake mod?

i was noticing today about how much better the v-brakes on my road bike work over any u-brake setup i have ever had on my bmx bike. i remembered that when you run a u-brake as a front brake on a bmx bike, it works as a side-pull similar to a v-brake. what if i ran my rear (straight) cable all the way to one side of my rear u-brake, through one arm and to a anchor on the other arm, similar to a front brake? might it have a better mechanical advantage?

friction at the last bend might be a problem, but i could use a Diatech flexie or one of those v-brake pulleys like this-


or with a chain, like this


is this a waste of time or worth trying?

I honestly don't know the answer to your question but, if it was my bike, I'd try it. What do you have to lose?
