Not really clear on your question, but I will give it a shot.
First, the playtest limitation on multiclassing a "hybrid" class with a "parent" class is being removed in the final version.
So, an Arcanist (wizard/sorcerer) WILL be able to multiclass with Sorcerer.
There are archetypes in the book, both for older classes, and for the new classes.
Archetypes only affect that class, so Tattooed Sorcerer changes your Sorcerer levels, but has no effect on your Arcanist levels.
So.....I hope I got you covered with that.
