Richard, I would do it differently, and have.
I wouldn't even bother with containers, I'd just heel them in somewhere and let it go at that, which I've done many times when I couldn't get around to planting a new shipment ASAP or wanted to rearrange some parts of my beds.
As lavandula said, daylilies are just about indestructible, and I could tell you the unintended abuse I've put some of them through, but won't, and they came out with flying colors.
