hrm. I have no way of drawing this at the moment, but here's a large improvement on your design.... you have the large and small idler gears permanently engaged, and you shift that last gear back and forth to make the shift. to do that, the last gear should be an idler as well, and engaged with a really long face width gear on the other side that it never disengages from. or it should be turning on the same shaft with a really long gear that won't disengaged from what it's turning. This way, you only have to move one gear. now, that probably doesn't make much sense, so I'll try to get a drawing together later today.
