I'm not sure I like merging translations together. They really make a difference, not like merging irrelevant things like paperback vs hardcover. A lot of classic literature from non-English originals (and I assume vice versa) suffers from old, dry translations -- I remember reading Dostoevsky in high school and not liking it much but that's because it was using translations from the early 20th century. More modern translations feel much more alive.
