Unrelated to your suggestion, but just a remark: stacking invisible pins on top is a very bad idea, as depending on the parameters of the pin, they may be subject to automatic connection by net name. If you're going to do that (I do, sometimes, in my own libraries), stack multiple visible pins, and hide the text by setting its size to zero.
