What are the query patterns? If you are versioning for auditing then changing the VersioningIterator seems the easiest approach. You could also store application-specific version information in the column family. One of the reasons that D4M does not use it is to allow application-specific uses. Using the CF means that any applications that understand D4M would not need to change their queries to adjust for the version information.
