Former Ireland player Morgan scored a superb match-winning century for England against his old team in the RSA Challenge one-day international in Dublin.
Morgan, 26, played 23 ODIs for Ireland before switching his allegiance to England and has since gone on to appear in 80 more, as well as 16 Tests, for his adopted country.
As Irish cricket grows in strength, it is a pathway that other promising players continue to follow with Boyd Rankin the latest ex-Ireland international to appear in England colours.
The matter is a problem for Ireland and is likely to remain one until they acquire Test status.
Morgan - England's stand-in one-day captain this autumn - was initially booed by the Irish crowd as he made his way to the crease on what was his old club ground at Malahide.
But he feels it is only natural that players should want to maximise their potential by moving to England and is pleased if youngsters are inspired by his and Rankin's achievements.
"Absolutely," he said, when asked if he wanted to remain a role model in Ireland.
"I think Irish cricket looks upon us with great admiration for the way we go about our hard work and utilise the talent we have been given.
"I certainly hope they do, although we have moved on paths we want to go down."
Morgan's extra experience and that of Ravi Bopara certainly showed in an outstanding fifth-wicket partnership that not only rescued England from a perilous position against Ireland but led them to a comfortable six-wicket victory.
Morgan and Bopara both hit centuries in an unbroken stand of 226 that saw the visitors recover from 48 for four to win with seven overs to spare.
"Ravi and I have played a lot of first-class cricket and a lot of list-A games," said Morgan, who finished with a career-best unbeaten 124 to earn a standing ovation.
"We have been fortunate to have played a lot of county cricket since we were 16, 17 years old.
"Our wealth of experience came in pretty good here. It certainly is a benefit having experienced the county game."
Ireland tested England by setting a target of 270, thanks largely to 112 from their captain William Porterfield.
It might have been more but for a good performance on his England ODI debut by Rankin, who was the pick of the bowlers with four for 46.
When Tim Murtagh took three early wickets in England's reply, Ireland had high hopes of repeating their famous 2011 World Cup win over their neighbours.
It was ultimately not to be as Morgan and Bopara, who cracked 101 from 75 balls, changed the game but it was still a momentous occasion for Irish cricket.
A near-10,000 crowd, the largest for a match in the country, attended and the growth in the game's popularity in Ireland appears to be continuing.
Morgan is pleased to see that, although he stopped short of saying England should feel a greater obligation to help by committing to more fixtures.
He said: "As an England player, we play a hell of a lot of cricket.
"I know the schedule is hard to get fixtures in. It would probably be better for Irish cricket to play more internationals, regardless of who it is against.
"But I have never seen an Irish game that has held nine or ten thousand. It is fantastic to see this sort of atmosphere and it is great for the Irish players to play in front of it."
Porterfield believes Irish cricket can take plenty from the occasion, even from the performances of two of their own in the England side.
He said: "That we can produce cricketers like that is great for Ireland.
"Obviously they are playing a lot of their cricket in England but the fact there are aspiring Ireland cricketers coming through wanting to be like them shows the calibre of cricketers we can produce.
"There were almost 10,000 people through the gate and hopefully the kids will be inspired by that.
"Cricket is growing in Ireland daily, and with every game we play.
"There is more hype around it and the cricket culture is developing."
