Card Caster, Kapenia Dancer, Hexcrafter: compatible?

[Daynen]

A careful read of these three archetypes suggest they might be usable together, since none of the hexcrafter's hex choices or the dancer's extra arcana actually REPLACE any magus arcana and the card caster doesn't touch any altered features. Perhaps it's ambiguity of wording, but as far as I can see, the features seem to have overlaps that provide things without actually altering or removing overlapping features. Viability of the combination aside, would this almost mythical class be legal RAW?

By the strictest readings, Hexcrafter and Kapenia Dancer are not compatible as both affect the Arcana feature as a whole by adding options to it.

Card Caster I need to look up.

[Ferious Thune]

Follow up. I don’t think card caster combines either. Since the other two modify Arcana as a whole, replacing a single Arcana conflicts.

If one replaced the 3rd Level Arcana (Card Caster) and the other replaces the 6th level Arcana, it would work. But since both the others modify the whole Arcana class feature, it doesn’t.

Hm. That's disappointing.
