My two-cents: keep it like this as it is still 8 months away; there can be other changes in the Autumn.

You can have another check before booking accommodations. IMO, AF/KL is usually quite generous in terms of schedule changes and they will usually grant you free changes even their flight is late by 1 hour.

Also, what would you define as "no longer fits you"? What is your current itinerary? Do you prefer having fewer stopovers? Do you prefer leaving earlier or later? Do you prefer CDG or AMS? Do you have to arrive at your destination by certain time?
