Nope. Still no idea what goes in the seven blanks. The middle letter must surely be an L, and the last an E, I or Y. There are too many variables for the word to fill itself in without knowing what we're looking for, and my psychic powers are a bit below par today.
One possibility that gives six real intersecting words is a British songwriter and broadcaster, Another is something you use in supermarkets. But what either of those have to do with this is anyone's guess.
I have a problem with the outlining too. to get 44 cells we need to include some of the letters that haven't moved, but which ones? There are several possibilities. This representation of the affected area is too crude for to link it to an actual map of the relevant area.
