I am afraid that's not going to happen, mostly because I'm not using windows anymore... So, I'm pretty much sure that I'm done with skinning...
Other than that, I can only add that you won't find dark theme for windows that are working properly. Fonts problem that you mentioned is the first thing but there are other similar problems, in certain programs, which are using they own skins or parts... In short, if you like dark themes and if you want to use them, then be ready to make certain sacrifices...
