In such a scenario, wouldn't the priorizer catch priority changes ?

ie, paths to owning SP are heavier than paths to not owning SP, so
changing the owning SP in navisphere would shuffle the path group
priorites.

If it is the case I would imagine the failback target to be the
externally designated one, which seems right.
