One other hack you can do.
Use a trigger with TTL pass through on the hotshoe (like the stratos or stratos II)
Mount an FP speedlight on the hotshoe and enable auto FP in the camera menu. (You can turn the flash right down in power so it does not contribute to the exposure and face it backwards)
Put your strobes on full power and fire with the remote trigger. You will need to control the strobe exposure either by distance to the subject or by aperture. It will steal about 3 stops of light, but I have fired regular strobes at 1/3000 using $100 triggers.
This is not a portrait, but a test shot I did. No real composition and no PP etc. It does illustrate 1/2000 @ f4 with a single strobe, using the hack I outlined above.
