Longevity will be an issue. You have to worry about UV inhibitors too for UV protection. Take Styrofoam dock floats or foam insulation panels. cut holes in them that allow you to place those black potting containers in them. Fill with hydroponic soil and then add plants. You can use adhesive to glue multiple layers of foam insulation sheets together, then trim to shape with an electric fillet knife. You will have to do the math to see how much flotation you will need, SWAG it, paying attention to what you think the plants will weigh when fully grown.

Blue Flag Iris, other marginal plants will do fine. You have to look at adult plant height when planting, tallest plants in the center, shortest plants on the outside.

Don't plant invasive plants like Yellow Iris, cattails, phragmites, etc.
