Here's a PHP script that will do it pretty easily with a bit of tweaking
for your use:

<?
  $releasever = $_REQUEST['releasever'];
  $basearch   = $_REQUEST['basearch'];
  $repo       = $_REQUEST['repo'];

  if ($repo == "os") {
    $mirrors = array(
      "<pathtomirror1>/$releasever/$basearch/os",
      "<pathtomirror2>/$releasever/$basearch/os", );
  }
  else if ($repo == "updates") {
    $mirrors = array(
      "<pathtomirror1>/$releasever/$basearch/updates",
      "<pathtomirror2>/$releasever/$basearch/updates",
  );
  // Add more repos here if you need them

  $mirror = $mirrors[rand(0,sizeof($mirrors)-1)];

  $path = $_SERVER['PATH_INFO'];
  header("Location: $mirror$path");
?>

Put the script on your webserver, then point your yum.conf like this to
your server:

[os]
name=Repo Name $releasever - $basearch - Base
baseurl=<pathtophpscript>?releasever=$releasever&basearch=$basearch&repo=os
[updates]
name=Repo Name $releasever - $basearch - Released Updates
baseurl=<pathtophpscript>?releasever=$releasever&basearch=$basearch&repo=updates

Tweak as necessary to handle legacy as well as any other updates.  One php
script can be configured to handle, just make up an appropriate repo name.

Have retries set to 20 in [main] of yum.conf and away you go!
