If I assume the standard seat width is 18", it's only possible when replacing 4 or 5 seats. So only middle sections could be converted into beds.
I don't see any problems in turbulences, if you are strapped in tight. But for take-off and landing, where you might have to get out of your seat fast, there needs to be a solution.
Although I like the fact of a flat bed in Y (and would consider long haul in there) this would come closer to cattle class.
