Sounds ugly to me.

Here's another suggestion: start-stop-daemon is in a /very/ good
position to know which PID belongs to which initscript. Patch it so that
it writes the PIDs to some "database"[1] somewhere; then patch
invoke-rc.d to be able to use that "database". Probably best to do that
through some well-defined interface, rather than having invoke-rc.d
directly reading out that db, though.

[1] "database", as in, "some way to store PIDs and which initscript they
belong to", not necessarily as in "libdb", and absolutely not as in
"SQL-engine with data files".

Fun will now commence
