 The data isn't there to make this possible, atm., in Fedora:

% sqlite3 /var/cache/yum/updates/primary.sqlite
> SELECT name,count(*) AS num FROM packages GROUP BY name,arch HAVING num > 1;

...and the primary reason for that is the the metadata download size
would explode, but we do have features like that we are looking at (for
situations where the data is there).
 But again, asking on this mailing list is not the best method of
getting new features or bug fixes.

 I'd also note that a bunch of the utilities in yum-utils make creating
complete local mirrors at a specific point in time, easier than you
might think.
