TDI Rap battles?

I have been watching the Epic Rap Battles of History shows on youtube and I was wondering, can anybody right a rap battle for some tdi characters.

Possible Ideas:

Cody vs. Trent

Gwen vs. Sierra

Duncan vs. Geoff

Chris vs. Cheff

Heather vs. Izzy

If you can right a rap battle for any of the above or some other people, post it below.
