Subscribe hooks can't publish client results, but start can.
There is not. All the gears can reach the same conclusion, and on start try to connect to the master if it's ready. You can also just make master election depend on an app env var value and have the start step check for it. The subscribe hook could also do a restart and wait for the master to be available - that has other issues obviously.
