The Netherlands! But Have Limburg as a State so Germany can Annex it, The Rest, Dutch Puppet.

Sounds easy enough

rest of africa ti mittleeafrika

*to

Then it wouldn't be in the mittel

How about Deutsches-Ostasia (German east asia) that can be formed Indochina and Malaya, maybe even an option to expand it by giving it Siam, Dutch east indies and the rest of Papua

also includes Tsingtao if possible

also i think you should remove the german claims on Limburg because imperial germany i think never had any claim on that area, instead add claims on former imperial territory and maybe cores on Danzig and Gdynia.
