@ Prfpi
I really don't want to take the wind out of your sails and I honestly admire your dedication. However and to give you an example of how strict Lufthansa is with the language, I know several people who failed the FQ (Firmenqualifikation, basically the second part of the admission for LH at DLR in Hamburg) just because their german simply wasn't good enough. These were all people who had studied german at school/university and/or had lived for some years in Germany. Either for studies or work.
As for my understanding, you will not stand a chance if you are not grown up in Germany/Austria/Switzerland or at least had the language spoken at home as your primary language.
However, there is still LH Cityline and Eurowings. Here you will be able to join with decent german skills. Good luck!
