I suppose if it were mine, I would first see what can be done in the printing. I would probably print the brightest part of the wall as Zone 7 or 8, bringing the Zone 3 parts up to where they should be. Sometimes burning in is the best way to keep separate scenes separate while keeping the contrast in each scene visually interesting. I'm thinking of the window, of course. I'm a little dubious that the window is small enough to profit from the increased local contrast due to stand development. The detail in the frosted glass, yes. The average level of the glass, probably not.
I could be wrong. There's a first time for everything. (If you believe that last statement. you'll believe anything.)
