I took a look on konqueror's home page and it doesn't look like there is any easy downloads you can build yourself.http://www.konqueror.org/download/
I know Arch has been successfull separating KDE components, but even they list the package for konqueror as "kdebase-konqueror 4.3.4-1"
Another Distro Chakra (which if you love exploring lesser know distro's is worth a look.) Is based on Arch and specializes in the kde environment.
They managed to split Dolphin from the konqueror package but here is how they describe the dependency chain.
split konqueror & dolphin packages (dolphin doesnt need anything besides kdebase, konqueror needs dolphin to be installed)
So even, if you split them konqueror will still require dolphin and dolphin required kdebase. So not much hope I think.
