I think I got a "proof of concept"

In functions_forumlist.php FIND

PHP Code:

}

// ###################### Start getimodcache #######################
function cache_moderators() 


ABOVE that ADD

PHP Code:

$forumcache[ID1] = $forumcache[ID2]; 


Where ID1 is the ForumID of your Link-Forum and ID2 is the ForumID of the destination Forum.
If you got several Forum-Links, repeat this line accordingly.

Let me know if this does work.
