While losing wandering spirit and wandering hex archetype do hurt some, I think the abilities the Name-Keeper gets in return are about what you lose. If you want to play a spellcasting-focused shaman, the Lore spirit is a good idea since Versatile Hex will let you pick up Arcane Enlightenment.
The Waves spirit would also be an interesting pick because of the Fluid Magic Hex and the way it interacts with the Pathfinders Past (Spells) feature.
Technically it is absolutely horrible, since it doesn't alter the Shaman's spells class feature at all, and the shaman's spells feature says that have to contemplate with your spirit animal to prepare spells, and this archetype doesn't have one, so you can't prepare spells at all.
Obviously that isn't the intent, and I doubt any GM would rule that way and I expect Paizo/PFS would clear that up but I do find it amusing.
Personally, I'd rather have a familiar than a broken wayfinder bonded object, and spirit animals are a little better than regular familiars.
The other trades seems more balanced, but I don't think they are quite as good as what the original had.
