LH is not going to very helpful here I'm afraid. As soon as the agent realises that this in an Aeroplan award ticket, you will be told to contact Aeroplan for any rebooking. LH is not going to touch reward tickets issued by others than LH M/M.
Buying o/w tickets with LH is always prohibitively expensive. Is is never half of the round trip fare.
