Compressing packages with bzip2 instead gzip?

Compression algorithms generally perform better the more data you give
them, especially 7-zip. Rather than compress each language pack
individually, I decided to try compressing them all as one unit. I
extracted all of the language packs and tared up and compressed the
resulting directory tree:
.tar: 184,934,400
.tar.gz: 61,478,589
.tar.bz2: 49,982,949
.tar.7z: 23,081,869
As you can see, 7-zip's compression REALLY improved with the combined
data set giving a space savings of 54% over the original .debs, and 43%
over individually 7-zipping each package. Are all of these language
packs on the setup/live cds? If so then compressing them this way would
free up 27 MB of space. I wonder what other packages this could be
applied to?
