Replacing a member of replica set with same host name

I am replacing a member of replica set (new member have different IP address). What i am looking to do is as follows:

RSYNC data directory of existing secondary node to new Node. Stop existing node. Map existing hostname to this IP of new Node. Start mongoD on this new node with replica set

I am hoping these steps will work. Could you please confirm the same.
