Yes, Ryanair already has 1 KIR based aircraft.
It is, however, questionable if it will last without DUB flights / PSO subsidies. Even with the continuation of these, I think it is unlikely to grow beyond a single aircraft.
A 2008 report by a consultancy saw passenger numbers rising as follows:
2012: 658,000
2017: 823,000
2027: 1,108,000
At the height of the boom, there were rumours about a Wizz Air flight to Poland. Can't see it happen now.
Perhaps an Aer Lingus flight to LGW?
