Summon Monster and other Templates

[The NPC]

Can you apply the lawful and chaotic templates to the monster summonable my the summon monster spells?

Also, are there alternate summons for those who worship the old gods or Desna? Would they work for a summoner?

[Cheapy]

Yes you can apply those, because the section in B2 says you can. The archives of nethys used to have an alternative summons list too, but I'm not sure if it still exists.

[Karui Kage]

It still exists in an offline format. I haven't gotten around to including that in the new site yet due to catching up on books, but since I'm down to 5-6 books now I may work on that section again. :)
