Coming from a V65, it's obvious she's not intimidated by HP or weight, but simply needs something that isn't too tall in the saddle. I'd say start her off looking at any of the 600s--CBR-RR, R6, Gixxer, new Kaw 636 (Mmmmm!!!)--and see how she fits. If she doesn't have a problem with those and still wants more HP, try the liter options. Worse case, she can always install lowering links; she'll still have way more cornering potential than the Magna she's riding now. FYI--She sounds like a keeper. If ya ever wanna turn her loose....???
