The main goal of most hashes is to give very distinct results even for even small changes in the input data, which is why there is not really an algorithm to compare two files' similarity based on hashes. Similarity of two files would have to be calculated based on something that currently isn't available - AFAICT. The savings in size are probably less important than the expectable performance loss for building deltas of source and/or object files.
