I am certainly no guru but I think you are on the correct path, however have you considered this:
You both have the same anniversary date: Correct??? 15th April 2012
Your points - 961, 39 to reach Plat
Wife Points - 239, 261 to reach Gold
OOL return trip gives you 190
If you give the 190 to your wife she will have 429 being 71 short for Gold.
This means that between 26th Feb and 15th April you have to find 39 points for you and 71 points for her. The million dollar question is can you do it in that time frame. Flexi return to OOL will give you 40 points. 1 way x J OOL will give your wife 80 points (if double status still in place) and then return fly saver. After this you both hit Plat and Gold and then you can then swap to have all future points go to you help you re-qualify for Plat.
Just a thought and hopefully I have not confused you. I would welcome other comments.
