I'd much rather see the Queensland teams play an annual pre-season Tri Series. Each team would get their two NRL sanctioned trial games, the regional centres of Queensland would get to see the teams they overwhelmingly support and have the most interest in, it would build on and offer an extra opportunity each year to exploit the "derby" rivalries (in the same way that AFL build up the WA and SA derbys), and it'd potentially be saleable to pay TV as a Charity Shield type product. A Queensland Cup (or whatever, yes I know).
Week 1 - Cowboys vs Brisbane @ Cairns
Week 2 - Brisbane vs Gold Coast @ Toowoomba
Week 3 - Gold Coast vs Cowboys @ Rockhampton
Week 4 - Rest
Week 5 - Premiership Round 1
Next year, swap the teams around so that the Titans visit NQ and the Broncos host the Cowboys somewhere in southern Queensland etc etc.
