The switch actually allows for an easier vertical configuration than the gamepad did, since you can take the joy-con off.
If they really wanted they could make one of those flexible holders you find on phone stands and add joy-con rails to it.
The holder would grab onto the Switch and you could add the Joy-con left and right in a Vertical configration. Sure, it might look a little wonkey and you probably wouldn't be able to charge teh Switch while playing, but it's possible.
