Yep .. just setup your own DirServer. See : 
http://tor.eff.org/tor-manual.html.en

(excerpt):

DirServer [nickname] [v1] address:port fingerprint
     Use a nonstandard authoritative directory server at the provided 
address and port, with the specified key fingerprint. This option can be 
repeated many times, for multiple authoritative directory servers. If 
the "v1" option is provided, Tor will use this server as an authority 
for old-style (v1) directories as well. (Only directory mirrors care 
about this.) If no dirserver line is given, Tor will use the default 
directory servers: moria1, moria2, and tor26. NOTE: this option is 
intended for setting up a private Tor network with its own directory 
authorities.

Cheers,
