Who Should The X Factor US Panel Cast?

Seeing as how X Factor US has seen nearly all of the staring panelist/cast fired... The question arises, who should replace Steve Jones as host, and Paula Abdul and Nicole Scherzinger as judges/mentors?  But first, lets take a look at some names that have been floating around who probably should not become a part of the singing competition's panel.

Anybody who currently is experiencing the height of their popularity, should all be ruled out.  There is no need to risk joining the show and stopping your current streak.  So that takes out artists like Katy Perry (who although would be a great judge-she's currently way too successful), Rihanna (way too young to be tied down to a show that could affect her top of the pops standing), and even Beyonce (though her music career is sagging, she is still in her prime). Now for those who'd make great X Factor Judges!
