Jon Bon Jovi has also been doing some acting (Pay It Forward and others I think) and he is pretty good - and look at Billy Ray Cyrus ( though he wasn't a rock star he did make a splash in country music and it turns out that he is a much better actor!) Scott has such a presence he would probably do well - but acting is hard so unless he has some natural talent - might not be so good - he did well in What If video no?
