Ouch - that is very cache-unfriendly.

If they are identical, how would I determine a preference? Or if they
aren't identical, how would I know?

That would mean (a) knowing all the versions that need to pull updates
and (b) copying a lot of stuff in the repo that nobody has installed
which seems a lot worse than letting a cache do its job.
Wouldn't this be better-handled by round-robin DNS, assuming that
the target hosts are not configured as name-based virtual hosts or
that they have the appropriate configuration to respond to the
same name?
