Can I Toss All Recordings From A Ch Project?

I'm happy with my first render test, and using the Character over in After Effects is truly a dream-come-true for me. I have everything set up for my character in this project, so can I (or should I) just delete all the recorded (sound and camera input) layers in my project, and do another output with new audio and puppet animations?
I'm sure it's a dumb question, but thought I might be missing something that I should have picked up on by now.
Thanks lots!
