I still think it's a good idea but it should be applied differently and for all parks. Let's decide on a reasonable distance from home plate for the batter to get credit for a home run. Let's say 380 feet. The line would be drawn from foul line to foul line 380 feet from home plate, across the outfield and through the stands where necessary. At least that would provide a way to judge whether a fly ball deserves to be a home run.
