Did you think about having both the laptop and desktop connected via the dock and then using the USB switcher to switch it that way? Then there wouldn't be any messing around with monitor source.
Is that even doable? It's the type of setup I want.

In any case, my desktop is old and doesn't speak Thunderbolt. I'm not sure whether I can bolt it on with a PCIe card, but even if I could, configuring an nvidia card to reroute output from its own ports to a Thunderbolt add-on card sounds... not fun. And then you'd have to deal with the fact that the longest passive cable that the TB3 spec allows for is like, 2 feet long, and I have a standing desk...
It's certainly an interesting idea, and pulling it off would be an impressive technical feat.
