Yes, I think Peter Jackson had Arwen take over Glorfindel's role and them some because he thought she didn't have a large enough role. Also, there aren't that many female roles in the Lord of the Rings. Sure you have Galadriel, but she comes across as untouchable. Then there is Eowyn, who is undoubtedly a wonderful character, but she's just one. Besides, Peter Jackson had to take in the fact that people who had not read the books were indeed going to see the movie--and that they might expect a strong female character. Peter Jackson had a tough choice there. Should he stay true to Tolkien or bring up Arwen and therefore have women play a larger role? Another point on that, he had to bring the love of Aragorn and Arwen into it or many people who do not like action/adventure movies would have been turned away immediately. So there's my answer, yes, Peter Jackson brought her up because not only did he feel that she did not have a large enough role but also that women did not have a large enough role.
