So I got my CLN replacement in the mail today. All things considered, this device is in pretty good condition. The only noticeable flaw is that the sim tray doesn't close if its empty. Otherwise its pretty much in better condition than the phone I have now. The lens even has less of a gap around it than my original One. Potential CLNers, don't despair!
BUT the the cam sensor problem is most likely still present; based on the /sys/android_camera/sensor file, the cam module in my phone and the replacement are from about the same time date in june (apparently post september is a solid chance of defect free).
So what i've decided to do, after talking to a vzw tech dude, is to send my original phone to HTC for repair while using the CLN as a loaner until I get it back. All in all, I think its a pretty good resolution.
EDIT:crap i hope my phone doesn't come back 4.3 and unrootable
