Ireland will be going for a fifth successive Home Internationals victory at Conwy from September 12-14 with the team to be selected following next week's Interprovincial Championship at Athenry.
Leinster will defend the title from August 29-31 with a host of potential Ireland players in their ranks.
West of Ireland champion Robert Brazill from Naas looks a likely contender for his first cap with AIG Irish Close winner Robbie Cannon also in the mix for a return to the Irish team following his victory at The European Club.
Brazill and Cannon are joined in Galway by South of Ireland champion Caolan Rafferty from Dundalk— one of the four leading players in the World Amateur Golf Ranking guaranteed selection— with Kilkenny's Mark Power another likely starter at senior level.
St Andrews Links Trophy winner John Murphy, South of Ireland runner-up Rowan Lester and Irish Close runner-up Eoin Leonard are unavailable for selection due to college commitments in the US.
But with Robin Dawson, Rafferty, O'Keeffe, Gleeson and Purcell all looking certain to play at Conwy, as many as eight or nine players will be vying for the remaining six spots on the team after the Interpros in Athenry.
