Does it really need 8 switches? How about 4 and maybe a couple other connectors on the other side, perhaps a serial port. Those things are impossible to mount on .1 space boards too, and really handy. I'm not sure of the dimensions but you could possibly make accommodation for either an Rs232 port or a parallel port on one side? I think they use the same standard zigzag pattern except for their mounting points. Maybe a pair of bus strips at the top in between the two screws as well.
