Hmm, RFC 792 says on page 15: "The data received in the echo message must be returned in the echo reply message". If not, the checksum will be different, which is part of the key to match the ICMP echo requests and responses.
If there's a valid reason to limit the payload size, it may be needed to tweak the PDU matching code.
