Given the limited utility of the tools currently available to us, editing the individual objects is our only option until they are updated/replaced. But once you have all the pieces imported they can be edited together and fit as they should. See attached example.
As for Player Serena's overworld model, I believe that it is stored differently than the others because of the clothing system. All the different parts are stored elsewhere. I don't know where though, I haven't found them yet.
EDIT: Or not... Modding for XY models for XY is easy, but I don't really know how XY's models work, so it's complicated to export to ORAS.
