Would it be possible to add the newly formatted book to Calibre, say Yes to adding a duplicate, then just merge them (right click, select Edit metadata, select Merge book records)? Or would them being the same format be a problem?

Then you can use the Modify ePub plugin to update the metadata in the new ePub. You can also do this while editing the medatada. Drop the new file in the list of formats or use the add button to find it.
A few things I can think to add to what you are doing:
- You can add books to calibre without a format. Or delete the format after adding it in. This is the equivalent of your placeholder in iTunes but calibre handles it properly.
- Have you considered using Sigil to edit the original ePubs rather than extracting the text?
- I would probably use multiple calibre libraries for this process. One would hold the originals with any metadata cleanup. I would copy this entry to another calibre library (using calibre) and then clean the ePub. When satisfied with the cleaning, I would move them to a third permanent library. I occasionally do something like this, but I skip the first library and keep the original external to calibre until I am happy.
