Um, no.
The longer the MP3, the larger the WAV that will be produced when you convert an MP3 to a WAV. As a rule of thumb, WAVs are 10MByte per minute of CD-quality audio (44.1kHz 16bit stereo). You can get smaller files without compressing by lowering the sample rate (which gets rid of higher frequencies - 22.05kHz is usually acceptable, 11.025kHz usually isn't), lowering the bit depth (you can sometimes get away with 8bit, depending on the music), or reducing it to one channel (you can usually get away with this without losing too much quality). A 11.025kHz 8bit mono wav will be around 0.75MByte/min. For reference a 128kbps MP3 is about 1MByte/min, and usually will be 44.1kHz 16bit stereo.
Bit-speed (or bitrate) has nothing to do with how large an uncompressed MP3 is.
