I know it's sacrilege to suggest a Camelbak to a road rider but as the spouse of a small person (perhaps smaller than yours), it's a solution that works. Filled with ice, a Camelbak is
better than any water bottle. It stays colder longer and it keeps the rider cooler.
As to the cage adapter, I see a bit of a fly in the ointment. Looking at your picture, there's not much room between the down tube cage and the seat tube cage. The cage adapter is going to move the seat tube cage a 1/4" or more forward which will interfere with the downtube cage. You may need another adapter for the downtube cage but that may move it forward and up too much.
I honestly hope it works for you but you may just be move swamp water and alligators around rather than actually draining the swamp.
