Hi,
We have 2-node SQL Server 2008 R2 Cluster. I'm going to add a new node with SQL Server 2014 and then, after some time, upgrade the cluster to SQL Server 2014. Does the scenario look real?
Cheers,
Andrei.

Bad things are going to happen if you try to fail from 2014 to 2008R2. If you failover to the 2014, you're stuck there until you upgrade the 2008R2 instance, so it's a risk

If by 'some time' you mean 'a few minutes', then yes. Otherwise no.

lets break this down
2 node cluster using which OS?
which OS on the node you intend to add?
are the existing instances clustered on the 2 node cluster?
