The only spot that likely works is behind LFL (again you have to get high enough over the 2nd row of LFL). Behind right field lounge the area you would want to put it has the light pole in the middle of it.
Behind 3rd base line, there used to be a batting cage and parking lot right against the stadium. now there is some green space, and it's possible but it needs to be very tall to get up to the stadium height and then clear the concourse.
If you did do both of these you could conceivably butt them against each other (down 3b line across back of LFL) .
1st base line is a lot more difficult due to the way the are dips down towards the hump (you would want something flat ideally) Plus the main sidewalk you would block.. plus trees you would have to cut down..
So all that work... and you would only need it for SBW or a Super Regional likely...
Links - Matt's walkthru, go to 12seconds in and you can see the full 3rd baseline from outside the stadium.
