Sorry if this has been asked before but could find anything about it.
I was looking through the witch's hexes when I came across the grand hex summon spirit which got me thinking if is it possible to summon spirits with spells like planar binding and planar ally? I know you can summon ghosts and what not through necromancy but necromancy isn't everyone's cup of tea. I figure that you might be able to summon spirits from one of the afterlife planes now you could make the argument that they don't count as outsiders but if that's the case just summon the spirit of a tiefling/aasamir. I know this still has a lot of holes in it but I wanted see what public opinion on this might be. Sorry if this sounds stupid but I thought it could be interesting.
