Is there open source code to convert losslessly CABAC into CAVLC?

Dear Experts

Is there open source code to convert losslessly CABAC into CAVLC and vice versa?
ffmpeg can convert CABAC coded H.264/AVC stream to CAVLC one but it does full re-encoding and might impact on quality.
In principle it's possible to convert CABAC to CAVLC and vice versa without re-quantization (although inverse quantization and inverse transform are necessary for reconstructed coefficients, in addition re-deblocking is also necessary).
