In theory, you could work a bit to make it "work": it's fairly easy to file the narrow notch a bit larger and flip the cogs. You would loose the ramps, which will make indexing a bit harder. Not impossible, just harder; for instance, you'll need to ease off pressure on the pedals to shift adequately, so shifting while going uphill will be a bit harder. How hard? Probably still easier than with a 1970s drivetrain.

However, don't expect miracles from flipped cogs. Worn off cogs are worn because the U-shape teeth flatten. Flipping cogs won't solve that problem completely. The chain won't be slipping off the cog, but will still "stretch" faster because cogs are worn.
