I am sure this can be done but it is not just a matter of changing the switch. You are correct that the standard switch is just up and down with two wires as this is just reversing the polarity of the motor and it changes direction.
However, the auto up and down requires a module to determine the voltage difference between up and down so that it knows what direction to turn the motor.
This requires a module that the switch feeds and the module determines what the voltage is and controls the motor accordingly.
Take a look at the wiring diagram. You will see the window switch has the standard up and down circuits but there is also an LED, auto, and ground for this switch that the standard does not have.

So that means you are going to need the window motor/module and the switch. Then you are going to have to account for the LIN bus that will get all the auto functions to work.
This is going to require the instrument panel as well which is where the LIN bus for this circuit is generated.
However, even if you get all these components, I cannot guarantee that this will work because I have not tried to do this swap. So again, while I am sure this can be done, it is going to take a bit of trial and error to figure out what these modules are going to need.
In short, it is more than just a wire hack as you mentioned as you are going to need a number of components in order to get them functioning.
Take a look at the wiring diagrams out of the 2010 with auto feature and let me know what inf you will need from here.
Thanks
