Agreed, especially if Matt Parish is still coaching Toa Samoa at the end of the year.
If nothing else, the combination of coaches should go a long way to building on the work that Aurelien Cologni did to try and restore pride in the French national jersey. We are more likely to see the top players make themselves available, and any players who are eligible via heritage also more likely to consider putting their hands up.
On the players they have in Super League, the strong home grown pathways, there's no reason - other than classic RL self sabotage - that France can't compete at least for 4th place on the rankings.
Toulouse stepping up to Super League, Elite One expansion, and Pacifique Treize are all cards yet to be played.
Tonga and Samoa will continue to rely on Aus and NZ immigration, I've seen nothing to suggest they are seriously investing in pathways from the islands to high level football, unlike PNG and Fiji. Tonga has the short term advantage but I would be very surprised if it sticks.
It wouldn't surprise me if by the mid-late 2020s, France, Fiji and PNG are the 4th-6th ranked nations.
