Sort of answered, it was the 'from scratch' I was half-worried about as some people may not have a backup of some books on their reader (not me I've learned that lesson!

As long as your assumption regarding author/title is correct, there shouldn't be a problem. Perhaps have a warning, if writing to device and both aren't included in template.
