Put some canola in with a Great Plains a couple years back. It had the Air-pro meter which is pretty much identical to the White meter. Worked good but need to have the hoses and meter boxes sealed up tight because those small seeds will sneak out if you let them. I forget how many cells the plate had but it looked similar.
I also know a guy who planted some canola with a White and he said it worked well, so it can be done.
