Greg Egan's Diaspora, Schild's Ladder, and Permutation City feel similar in scale if not exactly style. I've just started reading Alastair Reynolds's books, and those are closer to the sort of space opera of Banks, and so far so good. If you like really long books, Stephenson's Anathem is mind expanding and vaguely parallels some of Egan's books in terms of concepts explored. Finally I'll recommend A Fire Upon the Deep and its sequels by Vernor Vinge. Also check out Harry Potter and the Methods of Rationality for a rationistic fanfic crossover between scifi and fantasy if you haven't already. You can probably use HN's search feature to find previous scifi reading recommendation threads for more.
