I see three possible solutions.

Have you actually benchmarked the performance hit? I'd be surprised if this was actually the factor make or break your application. A second possibility is the RequestHeader directive, but I believe you would need to use the "early" keyword to make it work early enough in the request processing phase, and that isn't available in version 2.0; it is only in the development version, 2.1. A third possibility is to write a simple module that would rewrite the request_rec for you. That's all the ideas I have.
