I'm just checking because search didn't have hits.
Has anyone used JTAG "chain" programming to flash two micros on the same circuit? I assume the nrf52s won't hold this up, but I'm not sure.
Anyone?

Nope.
I made a fully working programmer for $3.80

Checkout my video www.youtube.com/watch where you see that I repurposed that STLink flash a WaveShare BLE400 with a nRF51822
Please checkout the Blacksphere's products. You can buy the Blackmagic probe from them (also via Kickstarter)
But they make their code available via the github (as linked above) for anyone to use as long as you have the technical knowledge.
You can give BlackSphere a donation if you use their code.
BTW. To Flash the Baite STlink dongle, you need a $2 USB to Serial adaptor (if you don't already have one, so you could fact that into the cost if needed) (umm you would probably need a soldering iron as well)
My hat off to you. You've done it better than I did.
No worries.
BTW. Thanks for the information about SWCLK not being able to be shared.
