Who would get what? Not sure. the Netherlands possibly st Martin. Maybe the Brits keep French Guyana, while they return British Guyana to the Netherlands (thus British Guyana would be Dutch Guyana, while French Guyana would be British Guyana).
Bourbon/Bonaparte/Réunion would most likely go to the British (just like the rest of the nearby islands), Saint-Pierre-et-Miquelon and most of the French Caribbean as well (excluding Guadeloupe, St. Barts and St. Martin who would go to Sweden, Sweden and the Netherlands respectivly). French India would also be awarded to Great Britain (it always bewildered me why they even gave those ports and factories back in the first place?). When it comes to the Guyanas, well the Portuguese/Brazilians would most likely get the former French portion.
And while we're on the subject of France's island territories, who get's Corsica?
