Anyone know if these are available separately anywhere?
Who were you informed this by ?
It sounds more like you are attempting to order these items on-line rather than through a real locksmith who would first properly identify the make and model of your mortise lockset to see if alternative trim pieces are in fact available, get you a quote on price, then order those items from the OEM through a parts house/supplier.
The answer to your question is yes, such parts are available, though not generally directly to the public. Replacement of damaged trim pieces is something that does happen in institutional and commercial facilities without replacing the entire lockset.
Without a bit more information about the lock in question, perhaps some pictures, etc, trying to answer this would be like asking a parts house for replacement brakes for your car without telling the parts tech what model, year and other details about the vehicle the parts are needed for.
