Much could be learned from soccer-style cheers and chants. As a Crew supporter since I can remember, Crew Union does a great job of posting songs/chants (

Additionally, they have a couple meetings, errr....parties, each year to go over new ideas.
Now, I have no clue what the O-Zone does, has done, or how things are done. What I do know is that using the KISS approach is something to consider. Make it easy for everyone to get involved without having to have to memorize a lot.
(another note - what effect is the relocation of the cheerleaders having here)
