Animal Companion Archetypes and Plant Companions(Treesinger)

[Celestial_Chameleon]

Ok it is 3:30 in the morning and I am at work and quite tired lol. I have tried looking through the forums to find the answer to my question, but have come up empty. Can the animal companion archetypes introduced in the animal archive be applied to the plant companions that a treesinger has? I mean looking at it I don't see any glaringly obvious balance issues.

I'm asking as there are people that will argue that "Except for the companion being a creature of the plant type, drawn from the list below, this ability otherwise works like the standard druid's animal companion ability." does not mean it is an animal companion and only acts like one, therefore trumping some rules that would effect an AC, like my question etc.(I have a few in my group that like to argue things like this until they are blue in the face)

Any help on the matter would be swell. Cheers! =)

Bump. Anyone able to shed some light on it? In particular I wanted to make the carnivorous flower companion take the racer archetype. Thus the question.
