Basically shift the focus from PCs and CHARGEN to the GM and campaign construction/support.
As soon as FFG does that, they essentially kill the line, because no players will be buying any of the new books. They’d cut the potential market by an order of magnitude for all further books.
Whatever FFG is likely to do, I think they need to keep the market broad and appeal to everyone, and not just the GMs or just the PCs. Anything else is likely to just wind up killing this franchise sooner rather than later.
The players who would not be buying the books are the ones who are already not buying the books. Most of the people who are currently buying would keep buying. Making the game easier for GMs increases the base. Player books do the opposite.
