I get duplicate lines from the output here - what about something like

for each in $(dpkg --get-selections | grep install | cut -f1) ; do apt-cache madison $each | grep universe ; done | cut -d\| -f1 |  sort | uniq > universe-installed.list

"time" reports
real    5m52.071s
user    3m26.669s
sys     2m21.925s

Comparison:

$ time dpkg -l|while read i n r;do apt-cache madison $n|grep universe;done|cut -d\| -f1 | sort | uniq > dpkg-universe

real    6m3.550s
user    3m28.509s
sys     2m21.753s
peter at prospero:~ $ diff dpkg-universe universe-installed.list 
peter at prospero:~ $ 

So it looks like both give the same result ...

There must be a quicker way though :-)
