So, as there are a couple of docks coming out that work with Switch 2 and have apparently reverse engineered the protocol... I wonder if some company could make a small dongle that just sits between the switch and my monitor, or my USB-C docking station, and fixes the communication.

For a DIY solution, protocol wise it doesn't seem too complicated, but electronically USB-C or HDMI is out of reach for most hobbyists. And I assume most USB-C interface chips you can get aren't programmable to the degree neccessary...
