The equalization would be wrong and there would be some loss of highs. 
Needless to say, if any two-sided processing was used in recording 
(e.g., Dolby B, dbX), it would be impractical to recover the original sound.

There would not be great saving in the process since resampling is slow 
if done well. Still, it's worth running your own test if you have the 
hardware and the patience. If you are only seeking a listenable version 
of speech, the savings may be great enough to justify the losses.
