I pretty much agree with Josh on this one. I think different sizes would be bad because of the bill changes like Extreme Burn, Hand Out 500, Heiny 500, and so forth.
However, I am in love with this design:

Here is the reason why:
1. It looks sleek and very professional looking.
2. It keeps the same presidents as always
3. In the background it has an image of a role the President partook in.
4. It's a crisp (no pun intended) design that I'd love to have in my wallet.
My opinions is that this design should be the same size, different colors for each denomination, and have an image of what that person helped do to change America.
Those are my thoughts.
