Can you elaborate? RHEL5's and C5's packages were known to be interchangeable. Without having tried it RHEL6/SL6 this is FUD.
I've written tools to turn an RHEL 5 box to CentOS 5, and back. It's a pain and I don't recommend it.
For how many boxes do you need to do this? I did this with some boxes and never run into issues.

I don't need to, anymore. I did it as a proof of concept for a few hosts of different architecute, offering to do it for a Beowulf cluster of roughly 100 hosts while we were arguing about licensing costs with upper management. This was a ways back, but the integration of yum for RHEL 4 was a particular adventure.
