Question on Qinggong Monk stacking with other monk archetypes

[Gaerum Daladd]

The Qinggong monk changes the level in which you can select several monk abilities. Does this prevent the Qinggong archetype from stacking with any other Monk archetype that replace the affected powers?

[Nezthalak]

Every monk is essentially a Quiggong monk. If you are stacking archetypes that replace the abilities gained by the normal vanilla monk, then the Quiggong can only replace abilities that aren't already replaced by other archs.

for instance:

Monk of the sacred mountain replaces Slow Fall with Bastion Stance, so you can't replace Slow Fall with a Q monk ability(taken by bastion stance), nor can you replace Bastion Stance with the Q monk ability (no provision for it in the arch description)

[Nezthalak]

bear in mind, your monk level must equal or exceed the level of the QM power you are looking to replace. so you cant trade wholeness of body (gained at level 7) for a level 8 QM power.
