May be you'll have two Lange in your collection if you sell your Moser and buy the "little" L1 but both this last one and your Saxonia are so different (both dressy as you said but the L1 as a much more sporty look for me and it's more versatile). Of course, they share the same DNA but they're, in my opinion, complementary.
I know that decisions are sometimes hard to take but we can feel that you really love and want to own this L1. You need to fund it so you have to take a decision. As Luis6 told you previously, listen to your heart and you'll have your answer 😉
