Actually that is pretty close to what i would think of for a docking station for the V - especially the cooling and ports.
I still would prefer that form factor to a box taking up space around the V even if it would be only about ports.
They attempted to put as much as possible into that thing, therefore the power bank and SSD and the induction charging...
But imagine having a 2 in 1 - like the V, passively cooled, decent performance, all the benefits of mobility and then a dock on which you place the V, connect it and you get ports to connect 2 monitors, mouse & keyboard, other peripherals, ideally still can use the pen in some drawing tabled mode + a GPU and additional cooling provided by the dock that would allow your 2 in 1 to perform as a decent desktop when needed. Icing on the cake would be some personal cloud/NAS functionality. I guess that would make it a 3 in 1 then
