Well, yes. Powerlaunch is fully programmable; you make the trade of a serious barrier to working with it for full control.

Possibilities, I suppose, include adding some simple and straightforward settings that would be translated into actual settings. (Can we parse a settings file in powerlaunch to accomplish that?) But, bottomline, since Nokia is substantially improving mce/systemui, that's probably the best bet for those who are only willing to learn enough to edit config files, rather than program. It was still a bit buggy last I used it (shortly before final release), so it's probably not quite back working completely, but it should be right shortly, and useful enough for such purposes.
