is lossless MP2 to MPC conversion possible?, goal: reduce bitrate of existing files.

The wiki articles on Musepack say that it's extended from the MP2 codec, e.g. Hydrogenaudio Wiki and Wikipedia

Does anybody know if it's feasible to losslessly convert MP2 files into MPC files?
If yes, does such a program already exist? (similar to mpc2sv8, the Musepack SV7 to SV8 converter)

Motivation: I'm asking this because I have many gigabytes of MP2 files stored on my hard disks. These are captured DVB radio broadcasts in 320kbps 48kHz stereo MPEG-1 Layer II format. I would like to save some storage space here and hope that Musepack with its more efficient lossless coding method can produce smaller files than MP2.

Saving 20% of the size is not bad at all! This would be the first case of lossless transcoding of a lossy format (since the vorbis bit peeling was never realized after all). Such tool would have a similar functionality as the lovely mp3packer, but for mp2.
