It's good to know that my setup seems to function as it should. I was dissatisfied with the varying required trigger time of the cameras in standby and half-pressed state.
When I flick my finger through the beam it is a very short event and it only triggers the camera every time when I set the triggers to a freeze time of 360ms. It does work most of the time with lower values but not 100% if I move my finger really fast.
It's just important for me to know that I didn't miss anything and have to compensate for the required trigger time by setting up the triggers differently or to just "wake up" the camera before I try to capture a movement with the triggers.
It actually does work if I half-press another off camera V6 TX in relay mode. I can hold it indefinitely and the camera stays half-pressed. The only downside is that it just works for one shot. When I half press the shutter release on the camera it works all the time. I don't have to re-half-press like when I use the V6 TX.
Another option to have the camera always "awake" would be to modify the shutter release cable by shorting the wires that go to the 2nd and 3rd ring of the connector. It should keep the camera always half-pressed and the time needed to trigger the first shot would always be the same. I'm not sure if there is a downside to this.
Thank you that you took the time to reply.

I use the Ray Flash Universal Ring Adapter. It works for me.

Thank you for your detailed Cactus reviews Class A. They inspired me to get four V6 and the LV5.
I have a question regarding the shutter lag. In trap mode my K-3 and K-5 IIs need a 360 ms freeze (freeze, dial on 12) setting to fire on the first event. All subsequent events after the first event only need 20 ms (freeze, dial on 2) to make the camera release the shutter.
My settings were: camera in M mode, automatic off disabled, manual focus, V6 in relay mode on channel 2, LV5 Sensor on channel 1. I flicked my finger through the beam to simulate a very short event.
When I "wake up" the already turned on camera with a half-press all subsequent events get registered with a 20 ms freeze time.
This works even if I wait a few seconds after "putting the camera on alert" with a half-press (or the first event which will get missed by the camera when the LV5 is on 20 ms freeze time).
As long as the top screen of the camera is still glowing it is still alert enough to respond to a very short event. After the top screen stops glowing this alert time is over. The camera needs 360 ms freeze time to fire on the (next) first event.
When I let my finger rest on the shutter release button of the camera to half-press it the camera is always in "alert mode" and will register he first event with only a 20 ms freeze time.
Is there an option to put the camera in permanent half-pressed/alert mode without e.g. using a rubber band on an additional V6? :)
