Given the fact that the massive typhoon class submarine is little more than twice the length of a German type IXB u-boat... It would not be and would not have been *technically impossible* to build such a Massive supply sub which could have fueled large surface ships etc.
From a strategic standpoint, given the nature of warfare during the battle of the Atlantic as it were in WW2, such a huge supply submarine would have been likely viewed as impractical.
The German failure in the battle of the Atlantic was not in lack of front line supplies alone. Even if the Germans had such a U-boat I don't think it would've made any difference
