That's really great!!
Zea (my wife) got her Unrestricted Bike licence (as it's called here in Aussie) last November, after spending a year riding her Honda CBF250 (250 Single).
The 250 was great for the year, as it enabled her to get her confidence, and when she did drop it (about 3 times - always either pulling off or stopping) there wasn't much to damage. Did replace the clutch lever once. (BTW - never tell a ladies age, but she is a year younger than me, and I was born in 1952. So she had a fair bit of learning to do, but she did start from the benefit of being an active and involved pillion for the last 7 years).
One of the very best things is that she went for lessons, and their focus was strongly on making her a safe rider, and the logical outcome was that she would get her licence (rather than the focus on getting her licence). Initially it was about 8 lessons of 3 hours ech, spread over 10 weeks.
I actively DID NOT TEACH her, but I did ask her what the instructor had taught her, and then we would go out a she would practice and implement what he had taught her. Sure, I would give her feedback, like she had been taught to move away from the centreline when cresting a blind crest, and if I felt she was too close to the centreline I would ask her about what she had been taught about road position, and how she thought she was applying what she had been taught, etc.
The 250 had it's limitations, though, and as soon as she was allowed (here she had to have her 250 licence, or Restricted Licence for a year) she tried my old Fazer 600. Again she dropped it a few times - again always when stopped, pulling off, or stopping. I had to replace both mirrors ($30 a pair on ebay from Hong Kong), and we decided to lower it for her. Adjustable dogbones were the go, and this just gave her the confidence she needed.
Three months on that and she was convinced this was for real, so we spent real money - got her own FZ6, and this has never been dropped - now has done 10,000k's in 7 months. This is stock height, and at the upper end of comfortable for her. But she has also ridden my FJR and FZ1, but she likes her baby.

So I say go for it, but watch for all the things you know are likely to be there: How will you (and she) react the firts time she drops the bike? How will you avoid the potential issues if play any role in 'teaching her to ride'? How will you cope with seeing her in such a vulnerable environment? (Oh, and when/if she does drop the bike, don't show any concern for the bike, only for her. Making the mistake of treating the bike as more important could be almost unforgiveable - I did that 30 years ago, and I think it took Zea 10 or more years to accpet that I was young and ??)
