Remember all those rumors that Obi-Wan was going to be a clone (original batch one) and that Ben was just a name to tell him from all the others?
It sounds daft now but with all those phonetically spelt droid names it kind of makes sense, even the clones in the animated series have personal names on top of their serial numbers.
Lando was going to be a clone at one point, I wonder if they kept shunting the idea along until they found a place that fitted better.
