Achieving higher shutter speeds in RC mode

[Unaware6905]

I need some advice. I have an Olympus E-M10 Mark IV with a Backscatter Octo housing, and dual S&S YS-D3 Duo strobes. I tend to shoot in RC mode. I am thus limited to a 1/160 sec shutter speed. However, in bright light and clear water, I might want faster shutter speeds to darken the ambient light for a more pleasing blue. Would this be an appropriate use for HSS (Super FP mode)? Obviously, I know I could switch to manual mode on my strobes but would rather use RC.

I have used it occasionally on the OM-1, but I can get faster shutter speeds natively. Seemed to work OK.
