If you want the most compact and versatile dock for all your USB-C devices check out this HDMI Hub called Switch-Con. Its already passed 5x its goal with 27 days to go.
Im not sure you should lay your Switch flat on its back like that, at least for heavy gaming. Those holes on the back near the bottom need air flow for the fan that pushes out the top. At least that's what I've been told.
it says it prevents over heat but int the way they put the switch on the table that actually blocks the vents on the back of the device causing more overheat so you need to put the switch with the screen face down to avoid that.
Looks like it hit 6X the goal and 26 days to go. It's crossing into that territory where the fulfillment will be more than they can handle so I hope they have a manufacturer to manage it appropriately.
