I've asked something similar with Gates, but if I have Cloudpost in play and have Conspiracy or Acane Adaption naming "Locus" with a bunch of creatures in play, will I be able to tap Cloudpost for a bunch of mana?
I'm assuming not as it's tied in with Lands type.

If I make lands into creatures as well, say with Life // Death with Conspiracy naming "Locus", will this work with Cloudpost?

Card Types don't share subtypes. Locus is not a creature type and is thus not a legal choice for Arcane Adaptation. Locus is also not a legal choice for Conspiracy because it also asks for a creature type. There is currently no, and assumed never, overlap among subtypes.
