Require advice/help with choosing ST devices to support the design of a "Wireless USB-C Displayport Alt-Mode System"

Dear ST Community, 

I'm drafting a "Wireless USB-C Displayport Alt-Mode System" that is primarily intended for detethering 3rd-party USB-C DP Alt-Mode devices. 

There are two distinct system scenarios, though I am mainly concerned with System Design 2 using a PC as the source device (Simpler starting point):

*Note:

As I understand it, we want to pass all USB-C DP Alt-Mode signals from the Source Device to the Sink Device, as we essentially want to be invisible to the original interface.  

Questions:

- What solutions can ST provide to overcome this? 

- Will System Design 1/2 theoretically work? And if not, why not? 

Kindest regards,

Jack
