I think under aer lingus regional branding they could make it work, they have done out of bristol and effectively driven ryanair out of aberdeen, although they would never admit that. I think under the RE brand they would be much more vulnerable, but I think the main cause of a bloodbath would be EZY on the route, something I can't see, but, I also can't see the airport expanding to routes all over europe but not to a main hub like DUB just in case of upsetting MOL. Somebody somewhere in aviation must have some balls!
