If you can find this itinerary for less than the advised price for Skyteam RTW fares, then great! But I really, really doubt a self-made itinerary would come anywhere close to the fares available for specific RTW tickets.
But it may indeed be that Skyteam no longer offers RTW fares (oneworld and *A still appear to do so).
Get a decent travel agent.
