you can have multiple urls on a single baseurl= line in a conf file -
that's just defining different mirrors. However, typically, that means
you have a local mirror, not a partial copy of some of the data.

If you really want to do that, I'd suggest copying the pkgs you care
about to local but making sure the metadata is identical to what's on
the upstream mirror. Then you can specify the additional baseurl and yum
will move through each of them until it finds a responsive/working
mirror.

does that help?
