I did that very thing as well, but now I want to go even further and get yet another one or two more, because I repeatedly need a #40 stop that is set to "flush" and another one that is set to Vans recommended .007 deeper for dimple-to-counter-sink situations for skins and such. Call me lazy, but that would keep me from mis-adjusting the tool to .006 or .008 or worse, if I had two #40 countersinks, with each one set to the proper depths for either condition.
But then I would probably need to remember which stop contains which depth, and then which gun has which stop in it, and so on.
As long as you label the stops properly, it might not be confusing, but I am old, so there are no guarantees!
