Another point, Stone Shape affects 10 cubic feet (one 10 X10 X10 cube) plus 1 cubic foot per level. Assuming the cohort cleric had to be at least one level lower then his 7th level leader, the max. volume that could have been effected was 16 cubic feet. I'm quite sure that a statue 70 feet tall with 15 foot diameter has more volume than that. Again, quite a generous judgement on your part.
