Interesting idea. Physics is not your friend in this venture. Steel can only stretch so thin and tune so high. Even the Line 6 Variax won't do this tuning, as alternate tunings shift its 12-string models to six string (I think -- somebody please correct me if I'm wrong).
Rather than tuning up to the high octave, tuning one string down an octave on the high E and B courses is the best I can come up with. Welcome to the forums, and if you find a way to do it, please post pics and clips.
