Alasce-Lorraine are as much German as California is Mexican!!!!!
Or, if we agree on your proposition, then a good part of Burgundy proper + Franche Comte shall also be add (As Himmler wanted that for his SS).
You are confusing btw population speaking dialects linked to old german, population with german culture, and german population! While Alasce-Lorraine do have population with german culture, most of the population were/are NOT german (the german population moved back after 1648 ... long ago it is not). While half of franche Comte dialectes are originating from germany; the population there is of french culture (since 1648 and La Couzon).
No reasons to adapt the map, but to deeply hurt a lot of people; none of the French provinces you named (and those I added ) were core province of Germany (But yes were part of HRE, as all provinces East of Rhone River ... 500 years ago).
One of the major points Germany made against France was the loss of these territories at the end of WWI (17 years prior). They form a very strong natural barrier and were coveted for strategic (not cultural) value when originally annexed after the Franco-Prussian war in 1870. The loss of these territories was seen as an insult to Germany (France felt very much the same in 1870. The fact of the matter is, during this century, both Germany and France had claimed the Alsace-Lorraine region as part of their rightful domain.

The demand for Burgundy/Franch Comte was not nearly as strong or widespread as the demand for the return of Alsace-Lorraine, which had in fact been a part of the German Empire for approximately 48 years only 17 years prior.
