I tried this overnight. I was successful!I didn't measure the time, though.
I've also tried a "minor" variation of this a few times. Memo, solve, sleep. More specifically:
1. Memorize cube.
2. Turn off lights. (too dark to see cube)
3. Solve cube.
4. Sleep.
5. Wake up in the morning. (now enough light to see cube)
6. Check that cube is actually solved.
Yeah, it's pretty much like an ordinary BLD solve, but you go to sleep in suspense.
I couldn't do that to myself.
