That doesn't affect me much but the different font on Hover and Peek does...

Actually I think the font of Hover and Peek looks really classy. I'm guessing it is Roboto Condensed. I'm sure you can't change it (yet) in Peek and Hover, but maybe you could flash Roboto Condensed across the whole system, like some ROMs in the Android Development Forum do.
