Elgato 4k120hz/HDMI 2.1 Capture Card idea

This would be expensive but would be extremely nice to have.

Having a PCIe capture card with 3-4 HDMI 2.1 ins and 1 HDMI 2.1 out. This would allow you to have at least your Xbox, Playstation, and Switch already connected to your capture card instead of having to switch them around and having to go through your wires and unplug your HDMI cable to plug in another one. It's up to Elgato if you can access all inputs at the same time but that would be fine to be able to do so. It would also be nice if you could access the pass-through without having to power your PC so you can just game straight away.
Thoughts?
