Hi Carl,
no offense, but maybe something you will not want to read: from your question I understand that you are not experienced in riding the Alps.
Please consider that the target points you mentioned all are more or less demanding. Some because of the track itself (especially Stelvio!) and all of them because in main season they will definetely be overcrowded with other motorcycles, bicycles, cars, motor homes, busses...
If you can, ride them early or late in season... and not without decent preparation aka training.
For your consideration and maybe help in planning your trip:

That´s over 600 POI, mostly in the Alps, that I visited since 2018. You can search and see what´s else waiting for you in that area. It´s not a complete list, of everything, but I guess I´ve covered the most interesting parts. 
Anyway, have a good and safe trip.
Regards from Austria,
André
