OK.
I tried my luck with the StarTrek Theme.
I did some work on it, but I can see that I'm not going to get this done anytime soon, so I'm posting the work I did so far and hope somebody will pick it up and continue.
I used Snoopy's install/uninstall package and just started replacing all the icons he made with StarTrek themed ones.
Whoever picks this up...have fun... :-)

Thanks.
