Guess it depends on the seniority first.
Which gateway--ATL, JFK or CVG? If you want ATL, try for the first one then rollover to the next--sometimes you get lucky that somebody else didn't make it to their connection!
You're pushing it a bit near Christmas, but since it's Mon-Thu (maybe get out before the 18th?) you may be fine.
The good news is it's grey and cold that time of year, so not the biggest tourist season!! There are all the EU Christmas markets tho--I'd check Paris websites for anything special going on that week.

Keep your options open to find out about taking the Thalys train to another city like AMS or BRU for that all-important Plan B to get home. You will not want to wait it out in CDG that weekend. I don't think the ORY (Orly Airport--the other side of Paris) flight is going to be on the schedule. If it is, consider that an option
Don't forget that CVG flight (IF it's still operating--should be--even with the merge!!)
I'd make some flexible plans and see what happens later.
