I think your being a little picky. CAM software will try to cut the tightest radius it can with tool specified. You should be able to cut 90% of the lightening holes with a .25 end-mill and then finish things up with a 1/8 end-mill. All in all it should take 8-15 minutes a plate with decent end-mills.
