What you just described should work fine. exclude._ip will move the shards off of the nodes you exclude but queries and updates can proceed while this is happening because the data is still on the old nodes. The updates will make their way to the new copies via a transaction log reply mechanism.
Depending on how the clients connect you might need to shift their connection uris to the new servers and that might require restarting them - depending on how your clients work.
