Interesting about those resonant power converters. And two of my favorite shows !
In the aviation world there are "Static Inverters" which are just DC to AC converters, typically 12 or 24V that generate 400 Hz at over 100V in single or three phase. They are used in the Cessna and other small aircraft to run the avionics instruments, the power output is around 40W. I think these could be modified to up shift the frequency to 1600Hz quite easily. Many types are discrete component 70's-80's vintage and easier to work on and modify than new ones with firmware.
When I looked at 400Hz three phase power units for ground testing of avionics gear it frightened me away with the prices, which is why I made my own with the VFD. Its a shame the VFD's won't go to 1600Hz, as they are a really cheap and workable solution.
I saw this which looks like a 1.5kW device that runs at 1kHz (it appears), that might be close enough and its output could be transformed down:

So it might be worth hunting out these types of devices for use or modification. I think this sort of thing would be easy to modify to 1600Hz:
