I hate to say, but I very much doubt that this will happen. FWICT it would require a new field in the DB, and frankly for minimal utility. And I say this from the POV that I am almost certainly going to be the one who patches it next. To be honest, I dont even want to support Aristotles "two-classes-in-one" tags.

But maybe a god will see your request and do the required DB stuff and then itll happen, but they have an awful lot of other stuff to do thats higher priority.

Sorry bud. It is a good idea on paper at least, but...
