Easy, rearrange the international calendar. At the moment we have a year where no or very little international Rl is being played, 2012.
On a four year cycle after 2013 have the following events at the end of the season. (IIRC from the next WC it will be on a four year cycle, five years this time as not to avoid with other events in 2012.)
2014: Four Nations (Australia/NZ)
2015: World Club Challenge based in Las Vegas (or other international city), as per Russell Crowe's idea.
2016: Four Nations (UK/France)
2017: Rugby League World Cup
Have the Four Nations every two years alternating between UK and Australasia as it is now, and theres your four year cycle culminating in the World Cup.
As for the format, starting with the winners of the 2012, 13, 14, 15 NRl and SL Grand Finals they will compete in two groups of four, plus semi finals followed by a final.
Where a team wins their GF more than once, that years entry spot becomes available to the other finalists within the four year cycle. If two teams are making regular appearances in Grand Finals then priority of places is given to other finalists within that four year cycle, then to the highest placed semi finalists based on final league positions in the final year. (Small chance of both semi finalists qualifying but possible if the previous four GF were contested by the same teams.)
If there are two finalists who didn't win the GF fighting for one place in a given year, then the most recent finalist qualifies.
For example, if we had had a WCC in 2010 then the English teams competing would qualify as follows:
2007: Leeds (Won the Grand Final)
2008: St Helens (as finalists)
2009: Wigan (as highest placed semi finalists)
2010: Huddersfield (as highest placed semi finalists who hadn't already qualified)
Like wise in the NRL:
2007: Manly (as finalists due to Melbourne's title being stripped)
2008:Melbourne* (as finalists)
2009: Parramatta (as finalists)
2010: St George Illawarra (as winners)
[size=50*- As far as I'm aware Melbourne weren't stripped of their runners up spot, only the titles they won. They would still technically qualify as finalists, otherwise Cronulla would take their place.[/size
