Hey Dug I'm glad you see it as a possibility! I think the two marry up fairly well together.
I think if it ever comes to reality you would need to ensure the off form features actually create options for boulder problems. It might be the case of creating a dummy reverse side from ply in workshop and purchase a host of proprietary holds. Cover the wall with these and get a "good" climber in to ensure problems exist and where improvements might be made. Then take a sheet of welded wire mesh or expanded metal and push it to trace or replicate this layout.
Then shape to add some 3d texture in the areas between the holds. Remove the mesh and spray with a rubberised texture finish to close holes in the mesh which then becomes the liner for the forms.
Really hope this becomes a reality.
