I don't think any of use have ever tried doing anything like that with transplanting in mind. But, I think maybe a lot of us have done something very similar when a scape blasts. I have on a few occasions used a splint and tape to keep a blasted scape long enough to see blooms. Now, I don't recall doing that when the scape had completely blasted to the extend it was totally separated, but it was hanging on by a thread so to speak. Still the buds bloomed. Now, looking at your photo, I would just suggest giving it a lot more shade and trying to nourish it back to health, rather than trying an experimental scape transplant. Still, you might make daylily medical history if you were to be successful.
