First of all, the plate is under tension, not compression, and is actually made out of relatively thin aluminum, so it is not under any great load to begin with, and no reinforcement is needed.
Only problems with your idea is that it is difficult to create the hole with a hole saw as the transmission case is fairly near the plate, and the transmission drain is actually off centerline slightly, so putting the hole in the correct spot is problematic.
Once the plate is out of the car and correctly marked, it is a 5 min. project to put the hole in the plate in the correct location. I also like to de-burr the opening, both to give it a more finished look and keep the plate from cutting your fingers the next time you service the trans.
