She won't be able to use the points @ OKW until the normal 7 month window. At that time, all points become equivalent and can be used anywhere.
If she has enough points to cover her vacation and yours, she can reserve OKW at 11 months ahead, no problem. Or if she wants to reserve at your resort up to 11 months ahead, no problem.
The problem is that since you can only move points in or out, she would need to make your reservation for you- you can't "swap" directly. And you will not be able to receive any transfers for the rest of your use-year.
If you are making ressies 11 months out, you must be pretty sure of the dates, so having her make your res in exchange for your points seems like an even deal (except OKW points are probably considered less valuable, since there is more likely to be availability at 7 months or less.)
Hope this clears it up a bit more-
