That's just what I was about to suggest -- hook into the 'bloginfo' 
filter, check against $_SERVER['HTTP_HOST'], and return different info 
as needed. Something like

   function twoblogs($text) {
     $hostmap = array( 'host1.example.com' => 'host2.example.com',
       'Host One Blog' => 'Blog on Host Two');

     if ($_SERVER['HTTP_HOST'] == 'host2.example.com') {
       $newtext = $hostmap['$text'];
       if (empty($newtext)) {
         $newtext = $text;

     return $newtext;

   add_filter('bloginfo', 'twoblogs');

In the $hostmap array, just put in mappings for whatever bloginfo 
strings should be different between the two hosts.

Make sense?
