Basically, you will have to add this functionality to RPCAptcache
You currently use get_installed_packages()

We need a function like get_corresponding_source_packages()

this would iterate over all installed_packages, and return a
list of the source packages, and additionally add a source
that was mentioned in a 'Built-Using' fields of an installed package.

This list would have to be generated for every component.

And this might also take a parameter with a list of binary packages
to consider (for the target component)
