I ended up getting two Dell 30" 4K displays and a monitor stand to mount one above the other, next to my laptops (also stacked), and that's been a pretty nice work setup for the past year. I did have to end up doing two USB-C to HDMI adapters plugged into the laptop to drive them, the docking station can't do dual 4K output (older Dell XPS15, sounds like the next version they made of it does).
