Hi there I have similar setup as you, to maximize the space I would say get Katana 100 and that will sort you out for good. Similar to 50 it has acoustic option on so you wouldn’t need two amps then. My room is even smaller and I managed to squeeze everything in, my top suggestion - hang guitars on wall that is a massive life hack and space saver.
I keep my desk in the corner with guitars above and next to it plus Amp and pedals underneath the desk. Big Ikea shelf on the other side for gadgets and other bits to store and chair in the middle 
hope that helps, if you go to my learning log there is a pic of my setup, recently I am upgrading my kit so this needs refreshing soon but gives you an idea
