No, I can't see any way that post-processing can undo the damage done prior. That damage is done at the stage of the single-bit quantizer as far as I can see.
The fact that many prefer DSD's sound is not in doubt, it really raises several questions in my mind vis-a-vis what implementation of PCM they're comparing it with. Nowadays most people do not listen to PCM via a PCM (i.e. multibit) DAC, they use an S-D one where the PCM is pre-converted into low-bit before the actual D/A. This conversion of PCM to low-bit brings with it some of the issues that L&V identify - i.e. noise modulation. So in comparisons between RB and DSD, the RB is already hamstrung with some of the drawbacks inherent in DSD. Not a fair comparison in my book
