With all the fallout from FlyBE, I reckon Dublin will be losing over 100K transfer passengers, most of whom would have used Aer Lingus.
What are the prospects of the freed up Stobart aircraft finding their way into an expanded EI Regional network in Dublin?
Cardiff and Southampton would surely make sense at least.

Flybe feed into Dublin is nothing like that volume, I'd be fairly sure of that.
Aer Lingus will reaccomodate the passengers from SOU, CWL and EXT via nearest gateways in the UK, BRS, NQY and London airports.
I would not be at all surprised to see Stobart pick up SOU and/or CWL, but slots are scarce and to use the Flybe slots you'd need a night stop in the UK or a late start from Dublin, neither of which are very attractive.
