I cant comment on FR specific SOPs (Standary Operating Procedures), but I can tell you that I can see no way you could save fuel from varying your landing technique. The set-up for the landing happens way back at the beginning of the approach and the speed/configuration would be roughly the same for any two 737-800s operating into the same runway at the same time with the same weight, no matter who the operator was.
There are a few exceptions to this, but it is unlikely that any of them would be used in normal SOPs so they dont enter into this.
In short, as Alex said, we can "plank" it onto the runway without a flare and everthing will still be OK (apart from you will think the pilot is really bad).
