The kid pools are perfect, and if exhibiting it in your yard make you shy, just bury it, cover it with a liner or it's side with a wall of rocks.
I think it's a little late to plant a bog (especially here, in Quebec), unless you are careful when you plant, to do not stress the plants. Since they are near their dormancy, it is better to let them gain a lot of energy and avoid stress (it helps to survive dormancy, but perhaps this stress isn't much critical as here...)
