i think a more eligent solution is possible. if you check out the (LARGE) screen shot of the Autumn OB theme in the OB section, it has two bars, one on top of the other.
...
i have just downloaded it. OB didnt want to tell me it was there at first, but i won in the end

the interesting thing about this bar is that the start button entends across both bars.
since i am only running at 1024 i had to dock the bars to make them show up, so be warned if you try this
by the looks of it my guess is how this was done was correct, just with a couple of refinements. nice to see that it worked for you.
a most interesting concept, but it takes up to much highly valuable screen space for my tastes.
