your plan wont work, unless your figure a way to selectively lock and unlock either the driveside and non drive side so that only ONE crankarm is operating at any given time.
Otherwise the larger gearing will dominate the drivtrain, and besides to enable your system to work you would have to physically make the rear wheel spin in reverse. I know people like Chris Hoy have strong legs but i think thats out of the question even for people like him.
invent a rear hub, fixed- fixed, that you could selectively chose either driveside or non driveside. It probably wont be popular cos it will be heavy, but this is your idea.

A viable alternative is to get a back brake. :)
