Since all the options are already available online, Paizo could develop 'essentials' characters, where they're fully Pathfinder 2e characters, but presented as a preset build path, ergo, instead of getting a choice of class feats at level 2, 4, etc you would just get something at that level decided by someone at paizo (or really, any of us online who can build characters with speed.) It would be fully compatible with Pathfinder 2e, and mirror essentials, but without actually adding different options (you don't need to circumvent a power system like 4e did, you'd just avoid feats that add too much complexity to the character.)
In other words, a player could be a Fighter (Knight), and that would just mean they're a fighter with a bunch of preselected feats curated to emulate a knight, it would make the presentation equivalent to 4e essentials / 5e, you'd just get a pre-selection of feats that make your fighter into a knight, instead of looking through all the options yourself.
Heck, the community could do this, fairly easily.
