There is always time to sell a Summilux BP. I would keep that one also because it is BP and you have a BP body. This kind of splits the obvious choice of keeping the most obvious complementary pair made by cron-sonnar. I would not see reason why the cron should not be your other keeper, besides buying a cheaper lens that delivers 95% of its image quality and regretting for missing that 5% sooner or later....and then you would miss the sonnar.....I tell you what you sell the CV, shoot with cron/sonnar and keep the lux BP as an investment 🙂
