I think the ideal way to resolve this would be to implement the mirror method for the apt source. Unfortunately the mirror method only supports fetching the mirror list via http (it does not support using a local file list). I've logged a bug upstream to include that feature: https://bugs.launchpad.net/ubuntu/+source/apt/+bug/1412758
