I'm no good at CAD/Inventor (yet) so I'm wondering how difficult it would be to use one of these to CNC Mill a flat stock of 1/8" aluminum into a sprocket that would attach to a hub. I want to do it that way so we don't have to spend $$$ on inch thick aluminum that's just going to get shreded. Is it possible to output the CAD design to a CNC Mill program?

I'd recommend you water cut them. All you need is as input is a .dxf line drawing.

Also, #25 chain has a 1/8" roller width, so 1/8" Al is a little too thick; it's likely to bind.
