Would it be feasible to do picture-in-picture in hardware? Digital video feeds, not super high-res, but needs to be updated preferably 120 times a second. Are there any single-chip solutions to this? I know text is pretty easy, but video sounds more than a bit trickier.

If you can wait til march, then one of these should do: https://www.crowdsupply.com/numato-lab/opsis
If you can't, then a bog-standard PC with capture cards would work, though latency would be a challenge. Or not, depending on your requirements.

you're looking for a thing called a multiviewer.
they're about a hundred fiddy bux for a basic unit that takes 2 1080p hdmi in and gives 1 hdmi out with pip and vertical split modes.
120hz frame rate is taking the piss though, there isn't even a standardised format for that.

there's no such thing as a format for framerates anyway, not in the traditional sense
It's just the same thing as the usual format, but faster

Whats your source? Whats your production workflow? Are you even producing? Whats the target output?
If you're bringing two streams into a computer then open the streams with ffmpeg, use a PIP filtergraph, and pipe the output to a virtual video device to be captured elsewhere
