How would you like the plants to live on your wall? Would they hang off the roof? Would they literally be connected to the wall?
Vines are good if you answer yes to the second question. Epiphytes and mosses would be good if you say yes to the third question. Other species could fit in if you think of another way to use a wall in the first question.
When you say "superadobe", are these, here and here, what you are talking about? If this is as strong or stronger than concrete, bricks, cob, or mortar, I do not see too much of a problem. What are your observations about "superadobe"? I would like to know more about it. As with all things, water is a powerful element. What are your current thoughts on protection from weathering and erosion?
