I expect Dr Saxton to canonize Imperator-class firmly in the Episode III ICS by taking whatever the next ship in the Star Destroyer evolutionary chain is and writing a blurb about the genealogy, for example:Lord of the Farce wrote:
IMHO, the fact that Acclamator-class, Mandator-class and Procurator-class is mentioned in the AOTC ICS is a pretty good sign.
"The Acclamator-class was the first vessel built by Kuat Drive Yards for transporting the Grand Army of the Republic Clonetroopers during the Clone Wars, building on the lineage of the Mandator and Procurator-class vessels previously built and used by KDY and countless other galactic fleets. Next in line was the Praetor/Censor/Dictator [three possible names I like]-class Star Destroyer, which was built alongside the Victory-class, by KDY's competitor, Rendili Star Drive. Following these vessels came the Imperator-class, more commonly known by it's slang term 'Imperial-class' by the Rebellion."
Simple. If he can get it past those WEG facists, we're easy.
