If I understand what you're saying, how does this sound?

For 2.5.0: add the ability to add a redirect, which effectively allows a package to be moved. Do not make any attempt to use this until the mirrors have had a chance to update.

Once all the mirrors have updated to software that supports redirects, then release version 2.6.0, and start implementing redirects. Now you can start to reorganize the directory tree, and instead of re-downloading, the mirrors will just move the packages around to match the redirect.
