I did that on the bottom edge of my 18.5 WSM.
It meant that I could close all of the vents and the coals would go out so I'm happy with that mod. I didn't bother with the door.
Of course I followed other recommendations as well like making sure that the middle section was as round as I could make it and fitting the door to minimize the gap. I also rotate the middle section on the base until the gap looks even all of the way around.
I don't feel like I'm fighting anything. I can easily dial in temps anywhere from about 200°F to 350°F.
