I looked at this a bit last week. The main difficulty now is that PPA ddebs don't follow their deb's overrides, so they are not correctly superseded. In particular pkg-create-dbgsym overrides the priority to extra.
The quick (and possibly best) fix is to override ddebs to match the debs even for PPAs.
