To expand on this, I did some preliminary investigation of the current
Trusty universe Packages file for i386 and amd64.

All of the architecture: all packages occur identically in both the
i386 and amd64 files.

Original (compressed.bz2) file size for both: 5.7M + 5.7M = 11.4M
Combining them and removing the duplicate arch: all packages and
recompressing: 8.9 M

So we can trivially save 15% by just merging the two files together!
