You are pretty much describing my dream solution for DJ!!
I think DJ need a 'SIA' to really show them how to deal with premium/high value PAX. And I think DJ would excel in operating an ultra LCC to combat JQ. Star Alliance... hell yea!
Interestingly, GD commented that in Q1 09, QF is projected to reach DJ's costbase which is a huge risk for DJ because QF are able to charge a decent premium (=profit) and DJ have injected cost into their business without realising a margin improvement (a wishy washy entertainment system and lack lustre premium Y).
