How would the interwar period have been affected if the following modifications had been made to the Treaty of Versailles (and Saint-Germain, in the case of my third point)?
1. Gdansk becomes wholly Polish (instead of the Danzig Free State) while Germany retains all of Upper Silesia.
2. Germany and Poland exchange their minorities (defined on a linguistic basis).
3. The Allies offer payments (equivalent to $10,000 in today's money) to encourage the Sudeten Germans to move to Germany or Austria.
