The QRU is responsible for running the game in QLD not the ARU.
No matter how many times it is denied by outsiders, the QRU has consistently and repeatedly insisted that the "Reds" ie. the QLD team is the representative team of the QRU. Why on earth would they be separated?
The former model used in NSW was to separate the professional team from the NSWRU. The idea being that the employees of the two were largely unrelated and had different KPIs etc. The Waratahs paid a licencing fee to NSWRU of about $1m a year. The setup was done partly so that there was a future possibility of injecting private equity into the Waratahs etc. It didn't happen and they reverted back to it just all being under the NSWRU umbrella (although I believe the Waratahs still trade as a separate entity wholly owned by NSWRU).
On the whole I think a lot of what needs to happen is that a lot of the back office staff for each union/pro team should be centralised because it creates better efficiencies. They are all too small to be able to effectively handle all the back office functions with the necessary levels of expertise without being overstaffed and too expensive.
It wouldn't be about taking away the QRU's responsibility for running the game in Queensland. It would be about trying to free up more of the QRU's budget to be spent on rugby rather than administration.
