i guess it all depends on the ledger being able to carry the stone. Its only going to be a cultured stone. and only about 4feet up the wall.
Cultured stone is it? Take a good hard look at wiping that brick ledge off completely and fastening the stone directly to the ICF surface. Cultured stone installed with mortar over wire mesh screwed to the ICF will put no load on a ledge. The adhesion directly to the wall is more than sufficient. I have about 3' of Owens Corning fake rock on my wall and there is no ledge support below it at all.
Now real brick is another matter altogether. It does need a ledge to rest on.
Different subject: I see from your pictures you have no screws in the field of the dimple membrane, only the screws and tabs at the top edge. Why not? I think all mfr's require, or at least recommend, screws roughly every 18" to 24" over the entire surface of the membrane. It looks like in one of the photos the membrane is being pulled downward by the stone at the bottom.
