It's cheating, somewhat, to replace your desk with once that is as wide as two desks. I'm trying to figure out a way to do something similar with only one desk's worth of space.
My desk is only 48" wide (4 feet / 1.2 meters) and 30" deep (76 cm). This is enough space to have a massive mouse pad with a full sized keyboard and mouse on it with enough space to the right of it to comfortably sit and work with physical items. The desk also has a 32" 4k monitor and a 27" 1440p monitor, a rack sized audio processing unit, a USB audio interface and easy access to a drawing stylus. I don't even have monitor arms either to save space, they rest on stands. It's also deep enough where if I wanted more horizontal space I could move my keyboard and mouse forward and have plenty of room to sprawl out a few physical items.
Long story short, what kind of desk are you working with? I would consider my desk fairly small but it has lots of room for common things.
