I finally did a rollout of this position with both double and no double. The report below doesn't say so explicitly, but the verdict was that White should double after 22/16 9/4 and after 22/11, but not after any of the top four plays. The biggest difference compared to the previous 3-ply/XGR rollout that I posted is that White is no longer doubling after 13/7 9/4. This fact pushes the top six plays much closer together.
