Your reasoning seems sound to me.
Up here, the cold snaps usually finish them off.
In Fl zone 9b, I would expect the impatiens planted in a well mulched shade garden to get frosted back but not killed...
I often see the plants continue to grow back from the roots, if the ground hasn't frozen.
As far as planting them now?
I'd probably wait until late February or early March...
