Here is my proposal for the MN reinforcement TFs :
Combat TF :
CA Algerie
CL Jean de Vienne
DD : I was thinking about Le Hardi class. They were designed in order to correct some defaults of the L'Adroit class : structural weakness in heavy sea, range, stability, AA...
But L'Adroit class is ok for me if it is JWE's prefered one

SS long range 1500t Pascal class
Support TF :
AS Jules Verne
AO Var
AKE US
KV La Batailleuse
Option 1 : CS Commandant Teste for air cover and scouting
Option 2 : CM Pluton as minelayer or fast transport
Troop Transport TF :
AMC Victor Schoelcher
xAP Cap Tourane and Cap Padaran
PG D'Iberville
Were already in the Pacific around NC and Polynesia :
KV Chevreuil
AMC Cap des Palmes
DD Le Triomphant
Some frenchies xAP, xAK.
For the onboard planes, i think we can keep the french ones until the refit in 1943 that suppress the capability.
Spares should note be a issue as there was important stock in Africa.
For the LCUs :
1 Foreign Legion Regiment with may be 1 Artillery detachment
2 bases forces, and yes, may be a small HQ.
+ some small units already in NC and Papeete at that time.
