Here's the relevant change to gitweb on repo that supports this:

   # owner link hook given owner name (full and NOT obfuscated)
   # should return full URL-escaped link to attach to owner, for  
example:
   #    sub { return "/showowner.cgi?owner=".CGI::Util::escape($_[0]); }
   our $owner_link_hook = undef;

And we use this hook:

   $owner_link_hook =
     sub { url_path($Girocco::Config::webadmurl).
           "/projlist.cgi?name=".md5_hex($_[0]); };

Replacement's a strong word at this point.  I've been looking into it  
ever since I found this in the Apache config:

   RewriteRule ^/c/(.*)$ /cgit.cgi?url=$1 [L,QSA]

So a cgit version of the cgit mirror would be http://repo.or.cz/c/cgit.git 
  (don't bother, 404 at this point).

I do slip in the occasional preparatory work [1] to make cgit support  
easier when I become aware of such things. :)

Looking at top, gitweb is clearly a CPU pig on repo.or.cz (git clones  
can also be piggy but I expect that to drop significantly when the new  
pack bitmap support is deployed).  And besides, the cgit display just  
looks good.  I'd like to add support for cgit to girocco [2] as an  
alternative to gitweb.  When that's sufficiently mature I'd like to  
deploy it alongside gitweb on repo for a time and then we can talk  
about switching.  :)

As you can see from the hook text above the repo gitweb hook only  
offers the ability to attach a link, it doesn't actually let one  
generate the markup or change the displayed owner name.  That's all I  
really need.  On the project list page [3] there are thousands of  
these, so running a shell script for each one is a non-starter.  A  
simple regex is not good enough either because it needs to generate  
the md5 hash (probably ought to be md5_hex(lc($_[0])) too -- another  
TODO item).
