They are actually the same code. Percona is Oracle's MySQL but includes the
google patches(InnoDB high performance and user statistics). Percona also
adds one more storage engine XtraDB.
MariaDB was a fork of MySQL when it began. Now it has a lot of changes that
make it quite different, again adding some of the Google patches and adding
new storage engines.
So all 3 packages generate the same binaries and libraries. So in fact they
are the same thing. Both MariaDB and Percona-SQL are drop in replacements
of Oracle's MySQL.
This is why I think of them as a replacement of the default MySQL. MySQL
stopped accepting patches changing the general functionality of MySQL when
they were aquired by SUN. So then was born Percona, it was needed because a
lot of us want the Google patches. And when Oracle aquired SUN, MariaDB
fork was born.

I have thought about building both MySQL packages as a separate daemons but
the problem is that since they are one and the same, they use the same port
,the same configuration files and the same data directories.
Althou that could be changed with a few simple patches this would make them
somewhat cripled.
Also the userland tools use the same configuration files (~/.my.cnf) which will
complicate things even more.
Is it possible for the EPEL policy to bend a little here for at least one of
these packages ?
