Personally I like this idea, however learning how to use an E6B is not the easiest thing in the world and I'm sure most people who play AH would be against this idea. If you like you can buy a mechanical E6B ($5-$10) and make your AH experience a lot more realistic.
I'm not saying making people use it. Picture this: A E6B, and its susbesquent fuel window, speed window, etc. The background is just an image, but inside the window, the numbers change. Its just like it is now, changing numbers over a background. Purely cosmetic. Although it would be cool if the wheels spun as variable changed.
IMHO, a picture of an E6B would be better than a tan sheet of paper stuck onto a clipboard.
Edit** Here is a quick cut-and-copy with Paint:

Maybe add some rate-of-climb and speed charts to the top and bottom???
