I always thought that the Reapers always had that design because it was fitting for their task or something like that. As for the fact that they made more Reapers out of the other races, well, I thought they used those for, erm... internal parts or something. Anyway, that was the original concept for that Human Reaper we encountered at the end of ME2. I thought it was a suitable explanation so I just pretend that's what happens in-game. It's better than no explanation at all, right?
