Should I trade Elton Brand for Anthony Parker?

I'm in a deep 20 team league, and while I don't really have a good shooting guard or small forward, both of which Parker is of course, what I really need right now is a rebounder, and what I desparately need is a shot blocker or 2. At some point, of course, Elton Brand will fill those shoes, but I need to balance that against the here and now and how much time I can actually expect from him this year. I'm also a believer in taking quality over needs (at least in the beginning of the season), so what would you do? I'd like to shop Brand around but I'm afraid this is the best I'm going to get.
