I really like your take on the bevel-beside wheel. It looks like it saves a lot of weight and space while eliminating some of the weaknesses in my design by putting the bearing around the turning gear and the spur gears below the turning gear. Overall this looks pretty robust.
It looks like you're missing a way to hold the CIM pinion on the shaft short of welding it on there, which I believe you can only do with a steel 11t pinion. Did you have another plan in mind?
Which gear did you need to make custom from aluminum? Or did you just mean modifying the turning gear?
What bearing are you using for the module rotation?
