Heh heh....
I see it as actually possible if you go ahead and get at least a 12000rpm spindle with coolant thru, use a solid carbide coolant fed drill that cuts right to final size, and use a solid cabide coolant fed 3-flute end mill (made specifically for aluminum). That would be just 4 tools to complete the first operation; end mill, drill, groove, chamfer.
