The RFL have said they are in talks with clubs from the Championship and League One over an early start to the season.
The governing body have also scrapped plans for the autumn competition, after only four clubs said they wanted to compete.
Instead, they are proposing regional group stages to start the 1895 Cup. This could include Boxing Day and New Years Day fixtures.
The tournament would then revert to a straight knockout after the completion of these group stages.
Mark Foster, the RFL’s Chief Commercial Officer, said: “Like everyone we want to see a return of our sport at this level. But in these uniquely challenging circumstances it is important that we work with the clubs to find the best solutions.
“Some clubs have already expressed enthusiasm for the option of an earlier start to the 2021 season, and the AB Sundecks 1895 Cup provides us with a possible opportunity to secure that.
“There is also the possibility of using the traditional sporting dates of Boxing Day and New Year’s Day to come back with a bang – although it is important we recognise there are still substantial challenges ahead as we work through the detailed requirements for the return of our sport outside Super League.
“Moving the majority of the AB Sundecks 1895 Cup to earlier in the season should also mean fewer midweek games in the 2021 schedule, which would be another potential advantage. With the Super League clubs agreeing to contribute to a prize money fund for this competition it definitely seems like an opportunity that we should continue to explore.
“Those discussions will continue over the coming weeks, as we all continue to work towards bringing Rugby League back for players and supporters to enjoy – although given the unpredictability of various aspects of the current situation, we are able to assess developments and the views of all clubs before making any firm commitments.”
