A character can take more than one archetype and garner additional alternate class features, but none of the alternate class features can replace or alter the same class feature from the base class as another alternate class feature.
Since Shapeshifter alters the second level combat feat and Wildstalker replaces the second level combat feat, technically, no, they do not stack.
That being said, I've observed it as a common house rule for the altered class feature to be ignored since it is replaced anyway. So, make sure to ask your GM but the default answer is, no, they don't stack, b/c of the bolded section above.

This is what I thought. Thanks.

Out of curiosity... does requiring a certain style actually alter the feats? A normal non-shapeshifter ranger could have selected Natural Weapon style, and shapeshifter doesn't change the feat selection or replace it or delay it or anything. It just affects the -style- selected.
It seems like the quingong monk, which says that it replaces certain options, but if you have an archetype that uses that option you just can't take it there, but they don't conflict.
Would you allow a Bladebound Hexcrafter Magus?

If a GM is a real stickler for the rules, then they will call the need to choose a particular style an alteration and not allow it. I've heard people say the same thing about the Quingong Monk.
Personally, I see no problem w/ deciding such things on a case-by-case basis and allowing it as a house rule, but you should never assume your GM will do the same.
