There's a few things you could do, such as moving a crew to SNN for a number of months, or operating on a W from Boston and hence minimal ground transport in Ireland. Crew are bussed up and down from Cork every day in the summer to operate EI's routes to Malaga and Faro!
The jump in capacity would be huge, I'm not sure there's the market for it. However would love to see the A330 back operating from SNN.
