Discussed this in realtime today. Rather than modifying the server to expose a 'latest' link, what I would like to see implemented in system-image server is support for a new "remote_si" (bikeshed the name to taste) generator which talks to an existing system-image server remotely, and walks the tree to find the latest image part (device tarball, etc) on a specified channel - using the full channels.json/channels.json.gpg/index.json validation chain that already exists. This lets us cryptographically ensure integrity of the download using client and server code that already exists, rather than requiring deployment of a new server feature on system-image.ubuntu.com that would only be used by the capomastro server and not shared with other clients of system-image.ubuntu.com.

And as a stopgap measure until this is implemented, we've recommended that PES simply mirror the content from cdimage.ubuntu.com via rsync and run the cdimage generator locally for imports.
