Remember when Steve Hed was experimenting with heavier wheels for descents. He did a bike change with Floyd Landis during the tour at the top of a descent and then changed back at the bottom.
If it can be even remotely argued for then there will be a visionary somewhere that will try it. Bicycles having been the focus of tech innovation for over 150 years or so have seen just about everything. I am sure there is a patent somewhere already for a crank that will easily change lengths. Bet someone even sold something like it in the 80's.
