Out of professional and personal curiosity, do you have any idea why not? As I don't do mileage runs I would never buy such a trip, but since apparently there are customers who would be willing to pay for this service, why wouldn't a for-profit corporation offer it? As they already do bookings with layovers (unlike for example EasyJet or Ryanair), offering BCN-DUB or LHR-DUB would also (seemingly) be rather straightforward for them...
