Have you looked at Xcode Build System Guide: Introduction, Build Phases, where it talks about adding custom steps to the Target build phase, including 'Copy Files', and 'Run Script' build phases. You can also create custom build rules scripts, see Creating a Build Rule Script.

Maybe something in there will allow you to do what you want.
