Too many ways for this to go wrong. If Aer Lingus changes its schedule it could mess up your whole itinerary. And if the flight from Dublin to London has to circle to wait for a landing slot or gate, your connection time could be reduced to less than an hour.
Another way to look at this; 2+ hours to get to the Amsterdam airport and go through security; a flight of 1h 40 minutes to Dublin, 2 hours on the ground there, then another flight, supposedly 1h 20 minutes. That is over 7 hours to go from Amsterdam to London even if everything is on time. The Eurostar train does it in 4 hours, city center to city center. I would not advise taking the train on the same day as a long haul flight home from London, but if you could overnight in London and fly home the next day it could be a pleasant and relaxing journey.
We are hoping that the air travel issues that challenged travelers this past summer ( long lines, missed flights, lost luggage) will not happen again, but there are no guarantees. I just read in the past day or so that Heathrow and one other airport (maybe Schipohl) are going to limit flights over the Christmas holidays to reduce delays, as they did last summer. That means existing flights could be canceled at short notice.
When is this trip to take place, and are you trying to book one-way?
