EDIT: One more question, what would be the pros and cons of machining the dog mates right into the hub of the gear as opposed to using a hubless gear and machining separate dog mates? I'm just thinking about less complexity.
The flanged bearings used are pretty beefy, they are about 1/4" thick so as long as your machining tolerances are good, there should be no wobble. You also want your tolerance very close on the bore of the output gears so that they dont' fall off the flanged bearings when they aren't engaged to the dog.

As for machining the dog mates into the gear, it is the way to go, we used separate dog mates and ended up welding them onto the hubless gears. Keep in mind that by machining them into the gears, the gearbox gets much narrower than if the dog mates protruded outwards. The dog mates themselves seemed more complex to machine than actually milling in simple pockets on a rotary table of a milling machine also.
