AlwaysOn with a single node possible?

This is a rare situation, but here's a projectplan I am currently evaluating. In my opinion this will not work. However, I can't find an answer. I found some documentation about setting up a single node cluster, but this is about a (traditional) 2008 cluster. This project is about migrating a sql 2008 cluster to a sql2012 alwayson solution. Here are the steps:

1. break the 2-node 2008 cluster. Production will continue on node 1
2. reinstall the 2nd node with windows 2012. install / activate clustering
3. install sql2012 with alwayson for this node only
4. restore database on 2nd node, test
5. promote 2nd node to production
6. reinstall 1st node and add to cluster
7. alwayson is working

So the question is: will step 3 work? Can you install / configure / run always on with selecting one node?
