What about their western aims?
Well, if Germany is sensible enough they won't demand too much in the west, as to not antagonize the British Empire too much. Britain was kinda fine with Nazi Germany as a bulwark against communism until they actually started WW2, so a 'merely' authoritarian Germany that doesn't go for genocide (and isn't too aggressive with germanization although some degree of that can be expected) should be more palpable to them.
That much said, they might still want Eupen and Malmedy back (assuming Belgium was dragged into the war as well, depending on politics they could get lucky), Luxemburg might be on the schedule as well (after all, it had been a member of the German Confederation until 1866 and member of the Zollverein until 1919) but any further acquisitions would be met with stiff disagreement.
And even if Germany wouldn't get any bit of metropolitan France it would probably still impose a demilitarized Zone in France and possibly the low countries (unless one or both of them were able to avoid participating),plus some occupation zones for a while.
For the lulz they might try to create an independent alsatian republic as a buffer state (so they can say that Germany didn't annex it after all) and have fun trying to prop that up.
Of course, I'm still assuming Germany being somewhat sensible. Even OTL the Meuse river was suggested/demanded to be the new border for Germany in case it would have won WWI, so a resurgent ATL Germany might just as well go for it, but that would antagonize Britain and especially France, Russia is already grumpy due to Brest-Litovsk II and having all those three as potential enemies is something which an at least somewhat sensible Germany should have the smarts to avoid.
