Just to clear something up. From what Hassan said the suggestion seemed to me, it might come down to a call on the day. I think you could potentially see her entered in all the events and then choose which one she chooses to start.
The final three days of that competition could look like this. Also notice how at the FBK Games this year she chose to do 10,000 1500 double in consecutive days. That could be seen as practice for this. It's an absolutely mammoth task but from the conversation we had she definitely didn't dismiss it.
10,000m final one day
1500m final the next
marathon the next morning.
