Cable link PC to Pico 4

Just an idle thought.
I currently have my Pico4 connected via USB-C cable through an adapter that links directly through the router and includes a power input. Easy enough to do, good vids available, and it has noticeably improved latency though does little else, especially graphics performance.

Folk have criticised the Pico for not having a direct graphics card connection and the current h/s only of course has the USB-C socket. But would it not be feasible to make some sort of adapter? I don’t know much about how these connectors work and also would guess some software changes may be needed.

Or am I being too simple-minded?
