Targets are chosen when a trigger is put on the stack. ETB triggers go on the stack before any player gets priority. This means, in order to even legally put Kitsune's trigger on the stack, two viable targets (two other creatures controlled by different players) must be present at that time to be targeted. Crewing a vehicle with Kitsune cannot be done in time as that requires prioriry which is only given after the trigger is put on the stack. Or in this case, after the trigger is immediately removed from the stack for lack of appropriate targets.

Full Control cannot help you achieve what you want here, as this is not a timing issue but simply impossible under the rules.
