Hello T,
Since (from memory) you already have a Canon EF 300mm f/2.8L you could get another one (subject to your budget, used) to make your life simple. You can go to Astrobin as a guide to what's possible from that exact lens and decide whether...

Here is an Astrobin link to some from one photographer using a Canon 6D and 600D... I would focus on the 6D images more as they are more of a torture test for the lens.

Well if you are really interested in a 135mm FOV then, you can go close with a 2x1 or 2x2 panel mosaic with your Canon 300mm on a full frame sensor, such as this image.....

or spring for a 135mm Samyang or Sigma Art lens.
