I can't see the ezy move happening but am confident that KLM would do very well with connecting traffic as currently you can only fly to Paris Orly which has far fewer routes to connect to but is better for the point to point traffic as it is more convenient for people visiting Paris. The LH routes would do well for both connecting traffic as well as point to point and would probably pave the way to more *A routes and ones from their partner airlines such as Brussles Airlines, Swiss, Lot(big Polish community in Southampton) and SAS.
