In short (see what I did there?), if the lead singer is a short-arse with a small ego, you are going to make him look tiny, a particular problem in genres like HM where the macho image is sometimes part of the deal.

Rubbish comment. Ronny James Dio, Glenn Danzig to name a couple. HM is no more 'boy band image' affected than any other popular music.
There are commercial acts whose image precedes musicianship (i.e. Poison, Motley Crue, Cradle of Filth) but they are far outnumbered by the people that try to make energetic powerful guitar oriented music and don't care as much about looks.
