For the sake of avoiding something you *assume* to be slow, or inefficient, you've taken the discussion in a direction that is vastly more complicated.
Why not just create NSString wrappers? By using the -initWithBytesNoCopy:length:encoding:freeWhenDone: method you can avoid it copying the actual C string characters, it literally just becomes a thin wrapper.
K.I.S.S.! If you can prove this approach is a problem by actual profiling, then OK, then you can talk about a more complex solution.
