Well, your example was assigning a tracker to a blank tracker Zekrom, hence my passage.
If I were to advise you, blank out all the trackers of the clones, then import them into B, to give them all unique trackers, then trade em away to your friends.
(if you clone the mon, the tracker is no longer unique. Hence the step below to give them all unique trackers)
To go back to my previous passage, B's HOME is expendable. Also as I said, HOME is able to gain access to other saves of profiles on the same console.
So going back to my example, inject the save into B, then deposit into B's HOME, then use B's HOME to withdraw into A's PC.
