I would just do a slow fade: -
Start by being regular meeting attendees, participating at the meetings and weekend field service.
After a few weeks, still attend meetings but leave early (after the first half). Every other weekend f/s.
After a couple of months: Miss meetings, attending only every other week and still leave early. Stop reporting hours in f/s
If people start questioning, say that you, your wife or kids are not feeling well.
A couple of months later: Miss all meeting - no field service.
Elders will start noticing - then say that you're feeling tired/stressed/depressed, struggling to cope with life, pressures of this system etc. You might get the odd shepherding call or visit but evenutally it would become to much of a hassle for them. They will reason 'well I called around and did my bit, so it's up to them now'.
A few months later - you are Inactive Publishers and successfully completed a slow fade.
If that fails - move out of the area!! That's what my we did.
