And the most important thing about HSS enabled pop-up is having the ability to trigger remote HSS flash.
It might be, but then you need to close the aperture half stop further and go from let's say 400Ws to 600Ws...
If your using portable flashes not studio lights then its irrelevant what you set the aperture to as far as flash goes.
Your point was you needed 1/250 to overpower the sun without ND filters and HSS was to weak (power loss)
I suggested bigger gun i.e more power to overcome hss power loss was a better solution as then you can use whatever shutter take your fancy to deliver the ambient/flash mix you envision.
Why would you
need to close the aperture half stop further
i.e if GN 12 in HSS gave you 2 stop underpowered @1/1000
then you would need a gun GN36 (assuming you use gn12 in master) or 48 if not.
If you had two gn48 flashes then you could shoot past 1/2000 still with the same power.
