Logisticaly this is doable - the precurser to this was the World League of American Football which lasted 1991-1992. Flying a Rugby League team, over costs less than a football (US not soccer) team and could be done on a commercial as opposed to chartered flight.
That said you have to be cashed up and the three words Sir Allen Stanford spring to mind so I hope for one due diligence is followed.
Also to be a big hit you need to have the best playing the best so IMO the prospect of a Wigan -Saints fixture at BMO Field where the Toronto FC soccer club plays as part of a British themed week with the Canadian club as apart of a double header would be an option.
Having the RFL's own version of the NFL international series with games at the Royal Dublin Showground and Scotstoun as well makes far more sense than continuing the tragic weekend but has unfortuantely has zero chance of getting off the ground under the current regieme.
Getting out of the Championship would be a priority though for Canadian expansion for once the novelty has worn off, the prospect of playing in front of palty crowds at Swinton and London Skolars will wear thin.
