That would require generating some 12K src-foo packages or filter
"apt* install" commands for src-foo packages and generate them on the
fly. Two things I found not so trivial. You also need the correct
md5sum for the packages file for apt* to accept your debs, so you are
back to generating all 12K src-foo packages in advance. Using a dummy
deb and wrapping dpkg-deb saves that.

Or you have to manualy create each src-foo deb when needed. That would
be simple too. A small wrapper around equivs to build the deb, then
dpkg -i and tell aptitude that it is manual.
