An interesting discussion about summoners of more specific kinds of outsiders, perhaps with the ability to summon outsiders beyond their own alignments came up in the Pathfinder Unchained thread.
This thread is to continue that discussion, and perhaps offer some requests to Paizo about some archetypes for such options, or even suggestions for GMs who want to homebrew their own.
Here's a quick summary of that particular thread below:

Or a neutral or evil character with a 'guardian angel' trying to redeem him. Or whatever.That's a pretty cool idea. Makes me wonder what kind of class abilities such an archetype would have in place of its regular features.
Not sure it would have to give anything up. Just picking an outsider subtype and a corresponding alignment isn't a power boost in and of itself.Maybe link it to the 'eidolon models' somehow so that if you've decided you want a LE devil for an eidolon, you have to buy evolutions listed for devils. Maybe reduced evolution points in exchange for certain free evolutions at various levels (especially if it's a racial power not normally available via normal evolutions, like maybe Genie eidolons could get wish 1/week at 17th level or something.)
But that's mostly to prevent characters that pick Angel and then make it a multi-tentacled horror with poison attacks. It could be left on the honor system.
This was a summoner archetype I created a while back that did this specifically for genies. I could imagine something similar could be done for Devils (with free curses) and Angels (free healings/miracles).
But I suspect the summoner talk might be a slight threadjack as there's more to the product then the one class.
