I was able to do this with mine. Now I can fit two kegs and my conical at the same time (I put the CO2 outside the fridge just under the drip tray).I'd have to start by relocating the compressor. I lose a lot of space because of the lip it puts in the back of the fridge. It's just something I don't want to delve into just yet.
if the bottom of the fridge was even with the compressor hump would there still be room for the kegs?
My keg fridge has a comressor hump and the former owner built a little platform out of wood that makes the floor level with the top of the compressor.
