This is an interesting suggestion, but seems like it is (a) a bit out of my league and (b) like it would bring up other issues, such as which coordinate system to use for interpreting the location given to the text function for the text object. The standard way this problem has been dealt with is to create an invisible axes that covers your entire plot and add a text object to that axes. Can this method do the trick for you?
