I find 4- 5 lbs a month more reasonable and I have done that before. Patience: 5lbs/month X 12 Months is 60 lbs.

In weight gaining, the turtle almost always wins out over the hare. Not that really rushing it for a while mightn't be fun, but people can burn out from focusing on one thing for too long (to really maximize short term gains does take a lot of focus, as you have to overcome your bodies instincts).
In really big gains there will almost always be plateaus along the way, so looking month to month even becomes less something to think about that year to year. If you think about how much she could gain over five years, for example, you see that while she needs to gain quite a bit each year it doesn't need to be an extraordinary amount per month.
(Of course, for a long term commitment to being fat, she might want to be in a long term committed relationship (i.e. married)? Gaining to that sort of size will really limit what she can do, so knowing that she has somebody who will always be there might make her more confident as her gain draws more notice and her size makes things more difficult?)
