I think so much depends on who he gets at DC and if he is smart enough to let them run their own show. First couple of years will probably look like Cal under Sonny Dykes where they are as capable of giving up 40 as they are of scoring 40.
Stanford has always been able to attract quality linemen so if he can continue that, I agree that he can eventually get them to be a tough out since the opportunity at a Stanford degree will always be able to recruit itself, NIL be damned.
