Castellated is the easiest lead design. Anything longer than the out side dimension of the part should be OK. However, you will never get an inspection person to say it looks OK, yet the solder joint occurs on the bottom side of the part - like a BGA. Save yourself some time and pick a QFP or BGA. A lot easier in the long run.
