You're making it far more complicated than it needs to be. An observer
moment is just a period of conscious experience. Usually it is taken to be
the shortest possible period, which for a human is somewhere between 100 and
500 ms, but there is no reason not to discuss observer minutes, hours or
whatever seems appropriate to the context. The "real" entity is the
observer, not the observer moment, but it sometimes helps to divide up the
observer's experience into time slices just as it is helpful to divide up
the day into hours, minutes and seconds. The division does not imply any
theory about how the brain actually gives rise to conscious experience, any
more than clocks imply any theory about how the planet rotates on its axis.
