I don't know. It would complicate things on versions, etc.

The EPEL version should be a lower n-v-r than the RHEL one.
However, due to the way koji works, when we setup a package like this,
it's the EPEL version on all arches that is seen/used in the
buildsystem. There's no way to tell koji to block a package in only
one arch or look for it in only some other ones.
So koji has no support for yum's "cost" parameter then? Assigning a
"cost" of more than 1000 to EPEL would get yum to prefer other repos
(e.g. RHEL) to it when there were packages of equal NEVR in multiple
