SPSM and the cloak are not the same thing. He can have 6PSM without the cloak.

Also Hagoromo designated Naruto as a meeting ground after they fought Madara/Kaguya, so that is irrelevant. He also designated Naruto the neeting ground before he knew of Sasuke's answer. So neither of these things were taken into account beforehand. With Kaguya having been defeated Naruto wouldn't have much of a reason to use the other Tailed Beast Chakra.
