You can use the 2b4 version of Midnight. The only difference is the background on one of the profile pages, which is an easy css tweak.
As for a fully reworked version, well I have a few things to do at the moment so extra custom themes are on the back burner. I'll probably start sorting them once I can test 0.956. It'll probably take a while because I'm planning on completely reworking some of the standard SMF templates that bore me. Mind you the theme could be released in basic form and extra templates added later.
