The seven counties who have submitted motions relating to opening Croke Park to other sports will combine their efforts in advance of Congress.
The Croke Park vote will dominate next month's GAA Congress
As expected, the counties have decided that the best prospect of change is to focus on the temporary motions from Sligo, Wicklow and Roscommon.
These call for Croke Park to be made available to the IRFU and FAI during the redevelopment of Lansdowne Road.
For motions to succeed, they need to be endorsed by a two-thirds majority.
While a significant majority of southern counties are in favour of change on the Croke Park issue, the vote on 16 April could well be defeated because of Ulster opposition.
Apart from Cavan, and possibly Donegal, all the other Ulster counties seem set to vote against an historic change and the opposition of the northern province could spell the death knell for the proposal.
The Roscommon motion calls for Croke Park to be opened for a three-year period from this April while the Sligo and Wicklow proposals refer to the period of redevelopment work at Lansdowne Road.
Roscommon official Tommy Kenoy has said that it would be "pointless putting forward seven motions".
"If the first one fails then the same thing will probably happen to the rest of them," he told the Irish Times.
"But even the temporary motions have a slightly different wording, so we'll have to decide which of the three is the most favourable.
"Roscommon are saying let it be opened for three years and then bring it back to Congress in 2008."
Waterford, Tipperary, Meath and Limerick are among counties who will consider the temporary motions in the coming days.
Current GAA president Sean Kelly is in favour of making the historic change but there is a difference of opinion among the two men who will contest the election to succeed the Kerryman.
Nicky Brennan agrees with Kelly's viewpoint but the other presidential candidate Christy Cooney favours the status quo.
