US Vice-PresidenT Joe Biden will be asked to chair a summit of US and Irish mayors during the 2016 Rising celebrations, the Herald can reveal.
Plans are in place to extend the invitation to Mr Biden and it is believed he is keen to accept.
Outgoing Lord Mayor Christy Burke has spearheaded the idea along with city councillors and a Dublin City Council official.
Taoiseach Enda Kenny and Arts Minister Heather Humphries, who has responsibility for the 1916 centenary celebrations, have been briefed on the proposal.
It is envisaged that the summit would take place in Dublin Castle over several days next April.
Mayors from towns and cities twinned with places around Ireland would then travel around the country with their Irish counterparts.
"Everyone is very excited about the plans," said Mr Burke.
"We're thinking about the bigger picture and the boost that it will give to tourism around the country."
He is also hopeful that visiting delegates could use the opportunity to scout locations that would be suitable for investment from US businesses.
Proposals to organise the event stemmed from Mr Burke's trip to San Jose last March.
There has been much speculation on the subject of Mr Biden's potential official visit to Ireland.
It was on the agenda during the Taoiseach's annual St Patrick's Day visit to Washington in March.
