I like this idea! I don't know how practical it would be, but I like the idea.

One area where it would help is in 2WD winter traction. Ideally you want a huge weight difference at slow speeds. Cars that I've driven with nearly a 70:30 weight ratio (more weight over drive wheels, whether RWD or FWD) can pull out of sticky situations nearly as well as an AWD vehicle. But once going down the road that weight bias becomes a problem since it contributes to oversteer and understeer. So being able to change that weight on the fly would be nice. Right now the only way to do that is manually moving around heavy objects like sand bags. It's kind of hard to put them over the hood though when you need the weight up front.
