Former Sligo Rovers and Cliftonville boss Gerard Lyttle says Danske Bank Premiership clubs would need a lot more detail and reassurances before they can consider giving the green light to All-Ireland proposals.
Twenty of the 22 top-flight clubs in the north and south have written to their respective Associations requesting that a proposal for an All-Island League be submitted to Uefa for consideration.
Dungannon Swifts and Cliftonville are the two clubs that did not sign the letter.
The IFA had said previously they do not support the All-Island League plans but the clubs have indicated they are keen to learn more about the proposed format before drawing any conclusions.
Clubs in Northern Ireland have been critical of the IFA over what they consider to be a lack of investment in senior football and this new initiative hints at a more attractive financial landscape.
But a lot of uncertainties remain, particularly while the game is getting back off its knees during a global pandemic.
His experiences in charge of Sligo and the Reds offer Lyttle an insight into the game on both sides of the border, but he can't get off the fence and nail his colours to any particular mast on this one.
Lyttle is now a youth coach at the IFA's elite youth academy in Jordanstown and the Association's reluctance to embrace any type of All-Ireland League is a major stumbling block.
But the overwhelming majority of clubs want further information and guidance from Uefa before making their minds up.
"Until we are clear what is on the table then no-one can make a decision," said Lyttle, who succeeded Tommy Breslin as Solitude supremo and steered the club to League Cup success. "These discussions have been going on for a while and people have very different views.
"I'm positive when it comes to anything that improves our local game.
"Whether it's a continuation of what we are doing in the Irish League or trying something different, I think it's worth considering.
"The Irish League in recent seasons has been a great product and it's getting better. With clubs like Larne, Glentoran, Crusaders and Linfield going full-time it's obviously going to raise standards and improve the quality.
"A lot more players from outside Northern Ireland want to come and play here and it's great for the league.
"But I would try anything if it improves the game. It's just unclear what the plans are and it's impossible to rush to an opinion at the moment.
"There's a lot of aspects to it. It's not just a matter of saying this is a great idea and it will work smoothly. There's a lot to consider, like travelling and the demands of midweek games."
The format agreed via Hypercube would involve a split season, with the League of Ireland and Irish League proceeding as normal for the first half of the campaign.
At an agreed cut-off point, the top eight League of Ireland sides and top six Irish League teams would go into the cross-border league that leads to a knockout series, which results in a victor crowned King of the Island.
Points picked up during the league section of the All-Island fare would also be added to the domestic tally, with a view to deciding the finishing places that determine European spots.
Teams who miss the cut would also enter into new competitions for the second half of the season with promotion and relegation issues at stake.
The intention is to preserve as many of the eight European places currently available for teams on this island as possible. But that will all be determined by Uefa's formal view on the experimental concept.
"People don't like change," added Belfast man Lyttle. "I think our league is in a great place and we have great teams, managers and owners.
"A lot of people are happy with the league and might be reluctant to take a risk.
"The European places have been a concern but there can be reassurances over that.
"There's one or two clubs that don't class themselves as full-time in the south but they are training three or four times a week, which is what full-time teams do, including games and recovery sessions.
"Football demands take up most of their week and in the Irish League players will do work in their own time, particularly on fitness.
"It was probably the most exciting league we have had in a long time and it's a real pity the league season was curtailed due to Covid-19.
"So many teams could have qualified for Europe and we missed the split games.
"We need to see more flesh on the bones with respect to the All-Island proposal and when we see that let's form an opinion. The focus now is to return to some sort of normality."
Cliftonville are still on a mission to lift the Irish Cup for the first time since 1979 and victory in Monday's last-four clash with Glentoran will give them a place in the July 31 showpiece.
"Forty-one years is a long time and I thought we were nailed on in the year we were going for the treble but it didn't materialise," added the former Northern Ireland Under-21 international.
