Once that system has been cross-pollinated, all bets are off. If you *have* loaded that baby down with updates and/or packages from Fedora, EPEL, rpmforge, sourceforge, etc., then you will likely have a bunch of head-scratchin' in your near and distant future. Un-bastardization is kinda like un-ringing a bell.
Having stuff on there from other repos isn't even the problem: As soon as you update *one* package on the machine, the centos media repository isn't able to satisfy dependencies anymore, as it only knows about stuff which is *on* the install medium.
