Don’t see why CDG should replace AMS, both have operated quite happily up here for a few years now, since AF returned to the route.

I was just thinking that with easyJet’s competition for point to point traffic on BRS-AMS, KLM would probably carry a very high proportion of transfer traffic rather than O&D, in which case AF and KLM would be ‘competing’ to a certain extent for connecting traffic at their respective hubs. Depends on the KLM route’s O&D/transfer ratio though, and I don’t have those figures so it’s just speculation.
