The Aviva Premiership Final could be brought forward to February to enable a new European competition to take place from March to June, according to reports.
Premiership Rugby and its French counterpart, the Ligue Nationale de Rugby, served notice last year of a desire to quit the Heineken Cup and Amlin Challenge Cup when the existing tournament accord expires next summer.
They want changes to the structure of both continental competitions, principally over the number of teams involved, the qualifying process and how funds are distributed and last week's statements from the governing bodies confirmed they would be forming a breakaway competition from 2014-15 onwards.
However, Heineken Cup chiefs claim all parties - including Premiership Rugby and their French counterparts - have "reaffirmed" commitment towards negotiations regarding a new tournament agreement.
It follows a meeting of European Rugby Cup directors in Dublin last week, when attendees included Premiership Rugby's Peter Wheeler and Rene Bouscatel, of France's Ligue Nationale de Rugby.
However, various changes are sought after including the structure of both continental competitions, principally over the number of teams involved, the qualifying process and how funds are distributed.
One proposal which is being seriously considered is to bring the Premiership Final forward a couple of months to February, which would allow a new European competition to be played from March to June.
"Potentially the Premiership Final could be before the Six Nations," a Premiership source told the Guardian.
"Then, if you ran a new Heineken Cup with the South Africans involved between March and June, that would be a pretty good competition for four months
"You'll hear people not just talking about a new European Cup but a new trans-border competition."
According to Mark McCafferty, PRL CEO, the issue of receiving approval from the Rugby Football Union and the IRB to form a breakaway competition, shouldn't be a stumbling block while the new multi-million pound television deal with BT has changed the 'whole landscape' of English rugby.
"There are still some people who will say: 'You can't have a cross-border competition without the permission of the French Federation, the RFU and the IRB.' Those people are living in the past," the source added.
"What has changed the whole landscape is the BT Sport deal because suddenly the clubs have got their own broadcaster and are bringing their own money into the game.
"The French will also be selling their equivalent TV rights shortly. The unions can huff and puff as much as they like but the reality is that the unions are not going to stop a competition bringing in £30m to £40m to rugby."
