BrianG, on one of my earlier Revo conversions I did something similar to what you described. I actually ran "L" plates on both sides to run dual packs. I then removed the motor side tray to better balance the Truck. As you said I drilled a couple of holes in the chassis, bolted on some blocks to give me a flat mounting area, then bolted onto that a plate that had a lip on the bottom to support the battery. It worked great and in my case sat about 30mm lower than the Tekno tray (which required me to remove the middle chassis support) which lowered the CG. With my current project, I wanted to keep the truck as stock as possible with no drilling of the chassis. Also the Tekno tray is really nice and I wanted to use it as is. Thanks for sharing your thoughts.
