I could potentially see this order happening but only on a very superficial basis. The minute you start trying to get closer to conflict or superego, things start going MAJORLY downhill.
In fact, when talking very superficial relationships, I would actually put Duality lower, and Activity & Identity higher, as Activity is more obvious of an attraction initially and is less awkward to start than duality, and Identity just bonds very easily over things they have in common.
Obviously when talking about close interpersonal relationships, of course you probably realize your list goes completely out the window. My list for closer relationships would look like this:
1. Duality
2. Activity
3. Identity
4. +/- Mirror (not sure, but i think intraquadra relationships tend to have more mutual understanding than interquadra)
5. Illusionary or semiduality (depending on subtype)
