A rolling harrier is a combination of all the manuvers that you mentioned and then some. You also need to be able to do a high alpha knife edge. You start in a harrier position then you tork roll to the left and as you turn apply right rudder. this keeps your nose up then when you are on the side it is a high knife edge. continue rolling around into a inverted harrier (letting up on the rudder) continue rolling slowly appying left rudder and as you finish the roll get off the rudder and go back to the harrier. This is how I do it, It may be the wrong manuver to what you want I think it is and if it is What kind of plane are you trying to do it with. I hope this helps
