??? while wave is technically a container format it´s usually used for
uncompressed samples so it´s lossless as well.

Wave has nothing whatsoever to do with the CD format.

Iff we are talking about the possible import format than that´s handled by the
library used to read sound files (libsoundfile should handle all of this).

But one would need to either keep the sounds uncompressed in main memory
(so no gain compared with the current setup) or uncompress them during playback
(with all the CPU-costs involvedin this).

For heaven´s sake - what for? That´s a dynamic range no human will ever be able
to hear/use?
Or did you just mix up bit-depth and (96khz) sampling rate?
