Don't do this at CDG....
As others have pointed out, 5:10 is actually not that much time.
In other european airports like LHR, AMS, etc. it is definitely doable an I have done this many times, especially if you are in J/F and have "Fasttrack" access. But CDG is one of the most disorganized airports in europe (IMO). So, I definitely wouldn't do it at CDG. The airport is also not that close to the city center. In AMS, for instance, you can be from the boarding door to the city center in 45 minutes if you take a train. Not true for CDG.
Enjoy the lounge!
