Not sure what might or might not be any good...It really depends on what you want to do/see on each location and on your traveling style. On first glance I think that yes, it is doable. It is fast paced too.
I guess you have decide those areas are your must sees, but personally I think you miss out a lot by not taking the time to explore outside the cities a bit. And I mean the non-touristy areas or not just a quick day tour.Killarney area is fantastic for example but you have only one full day there excluding the Ring of Kerry day and arrival/departure days. I find parts of the trip too fast paced too, such as the Ireland portion. Galway to Killarney is a long way and you seem to criss-cross the country from/to Dublin missing great parts. Personally I could pleasantly spend one week on major destinations such as London,Paris, Rome and at least 5 full days in Dublin, but as I said, you do not mention your motivation for allocating such and such days here and there.
As a side note, have you ever travel that long? I often take 3-4+ weeks trips and on my experience after 2nd week you really need to plan for some down time and take it easy. I take such trips since my early '20s and I am now 31 years old and quite active, so take it for what it is... I would try to have a chill out/free day planning absolutely nothing every 5-7 days of hectic sight-seen/traveling.

I agree with Mariha about spending one week in major cities. You have 3 months, so why rush? For example, we just spent 7 nights in Paris, including a day trip to Versailles, and we still did not see everything. Many years ago I was in Rome for one week with a very rushed day trip to Florence. Never made it to Venice. Make sure to leave yourself some time just to wander around these beautiful places; don't just run from one attraction/museum/monument to another. Slow down a little bit; otherwise, everything will seem like a blur. I also agree, even if you are young, that you need downtime to rest after sightseeing. Travel is fun but tiring, too:-)

You seem to spend about the same amount of time in cities. Is that based on an idea of what you want to do there or on an effort to evenly allocate your time?

London, Paris and Rome definitely deserve more time than, say, Berlin and Dublin IMHO.

Make sure you are leaving enough time each place to do the things you want to do.

i really don't know why someone would think -- without knowing you -- that Berlin doesn't deserve as much time as London, Paris or Rome. It's a very complex city that is deeply rich in history and contemporary German life, and has more than a week's worth of fabulous museums.

Your current itinerary has you going very far north in some of the coldest and low-light weeks of the year. Can you reverse your itinerary so you see places like Amsterdam and Ireland in November and Italy/Spain in February?
