Sounds like a good idea in theory but can't be done unless Brisbane transfer his sportsmans visa to North. This can be done but North then have to pay the player a min amount, not just in cash but in Housing, Car, Medical, Dental plus take on his cost of a return ticket home.
Whilst the salary cap is in place it really cant be done unless he only plays a handful of games. I think the salary is about $350.00 per week + the other stuff.
If the salary cap wasn't there they could do it provided Brisbane transfer the sponsorship of his visa and North had the cash to pay him. These restrictions were put in place by Immigration to stop Imports coming out and basically living off the street if the club failed to pay them etc.
