I'm not sure that I follow. Are all the records in 0RTT going to use a content of handshake, or just the Certificate/CertificateVerify/Finished? I assume that you meant just the handshake messages, in which case yes, this is OK. It does make identification of what goes into the handshake hash marginally more difficult.
With your client authentication changes, you could just concatenate up everything with content type of handshake. Now you have to be a little more selective.
