The walk-by I was talking about is simply not working.... But I may have another idea.

Let me ask this question.... If we go through with this Maul/Grevious idea, would it be acceptable that maybe Maul received new eyes resulting in the eyes he has as the general? Maybe his old eyes no longer function due to the fall?

It seems we need some type of connection between Maul and Grevious to bridge the gap. The eyes always seemed to be the best (or easiest) way to do this.
