I like that idea too, that way we're not repeating the same pairing, with both of the girls being the younger siblings.  It'll give a different perspective too, having the older one being the opposite gender in each case.  I don't mind Marie being the same age as Jack, which gives Matt the option of being a bit older, if Eeyore wants to play him in his later twenties.  I can't remember offhand what Jack does for a living, was it a lawyer?  I could be getting that confused with something else though, so straighten me out Leo, if I'm totally off!  ^_^
