Actually, your design is one that is favored by many references. It is much
less critical of alignment, and, as you have noticed, it spreads the arcing
area out.
There are also all sorts of games you can play by angling the stationary
electrodes relative to the moving ones (i.e. nothing says they have to be
parallel to the rotational axis of the rotor.). This has the effect of
lengthening the time the gap is close.
