Is it possible to change font/notification bar without root?

[heyitsericc]

I don't want to void my warranty until it expires, so is there an alternative way to change the font, mainly for TypoClock and other word widgets, and notification bar? I'm using LauncherPro, and there is an option to hide the bar, but the bar lags along and makes the whole screen tilt a bit down to compensate for the bar. Don't think you understand me

Also, any good reccomended icons for LP?
