Hi David,
You could try Freedora, however, I suspect it may break some programs as
CentOS is, contrary to popular opinion, different from RHEL and Fedora.
There are quite a few additional programs and scripts they add into the OS
that RHEL and Fedora do not include.
It could be possible to remove the added programs from these CentOS specific
repos.: (under section 14 of Q&A)
https://wiki.centos.org/FAQ/General#head-4b2dd1ea6dcc1243d6e3886dc3e5d1ebb252c194
Also, there are quite a few changes going on over there, they are in the
process of being taken under the wing, so to speak, of RH, and over the next
year they will launch a "new" CentOs with changes from this "merger". You
may find these links useful.

It will be interesting to see how much it can remain a "community" program
now that RH has direct influence over its Board of Directors.
PS: Most of the people involved with Blag are running Fedora 21 or 22 with
Freedora. Which is basically Blag anyway. They are working on removing
SELinux and other items from the next Blag as well.
