It's not entirely trivial to do, but possible nonetheless.

So, let's say you downloaded the ubuntu trusty amd64 tarballs, you need to do:
 - mkdir -p /var/cache/lxc/download/ubuntu/trusty/amd64/default/
 - copy rootfs.tar.xz in /var/cache/lxc/download/ubuntu/trusty/amd64/default/
 - unpack the content of meta.tar.xz in /var/cache/lxc/download/ubuntu/trusty/amd64/default/
 - Then run the download template with: -d ubuntu -r trusty -a amd64

It'll then tell you that it found a cache copy and it'll use it rather
than attempt a download.
