Try using WavPack, http://www.wavpack.com/ This can losslessly compress 32-bit floating point WAVE-EX files, and faithfully preserves every chunk (which FLAC does not do). It is also free.

...inds strong matches (under a certain threshold, and starting with a couple of matches), the frame is saved to a pool, and it's subtracted from the song. Then you FLAC the (small) pool, and the song, full of near-silent spots (& silence where pure repetitions occured). At decode time, you unFLAC the pool and the song, and you add back the frames from the pool to the song. I haven't experimented yet, but let's say I try to correlate frames with the song, and I get something like 20 near-repeats, I may end up with a very silent "song leftover", still as long as the song...

This might work, but you would have to be very lucky to find matches given the block size of FLAC (or the frame size of any format, for that matter). But, you're right, if you can predict the waveform with...
