I'm sorry, but I personally think it's practically impossible to play in Europe with such a small squad and still compete in the Premier League without any problems. Most clubs that play in Europe could even play their youngsters in their national leagues without being relegated, because there is such a big difference in quality between them and other clubs in the league (I don't think we fall into that category). And even the teams that don't face such strong competition at home often limp into the winter break with their last ounce of strength and many injured players, where they can recover for two months. But well, I'll wait and see – maybe I'm being too pessimistic.
