Just use a leaf shutter with X sync. Enjoy the focal plane shutter with barrel lenses. If you are determined to use the shutterless Aero Ektar with electronic flash, a front mounted Packard as has already been suggested is the best approach.
I need to dig into the wiring of HSS strobes. It's probably not something as simple as a contact closure, but it might be possible to control it with an Arduino or something like that. I fear you're right, Oren -- that HSS won't last long enough for the relatively slow shutter speeds of the focal-plane shutter.
The Pacemaker Graphic and FP bulbs was only for fast shutter speed: 1/250 and higher.
It might be. If the HSS setting is made on the flash rather than from the camera's menu, and the exposure mode is set for manual or for AE controlled via on-flash sensor rather than camera-controlled TTL AE, there might not be anything that needs to be communicated between camera and flash other than sync closing. In theory the duration of the HSS pulse sequence might be customized to different camera bodies via some signal through the dedicated flash contacts, but in practice I suspect that it's a fixed parameter.
The ez, old school way is to use bright hot lights, and use any speeds you can meter...
