Magus,
If I had your money to spend on two MPs and only two lenses:>
1. MP .58 + L 28/2 or ZM 35/2
2. MP .85 + L 50/1.4 or ZM 50/2
I haven't indicated the finish, but I would prefer the SC for both because of the classic look and the way it wears. The 28 or 35 would be a tough call for me; right now I would go with the 35 biogon, it has such a great tonal signature and the FL is more versatile for what I shoot. Doing so would also help me to save some of your money. The two 50 lenses are both awesome, and I am glad that I don't have to choose between them, but if I was buying this stuff for you as your steward, and I had to bring you just one, I think I'd bring you the L 50/1.4, as the speed of the lens gives it a bit more versatility than the ZM 50/2. But if you'd allow me to find you a good used L 50/1.4, and spend the savings on the ZM 50/2, then I would do that.
Have fun choosing your minimalist step up, Magus! It has been a blast thinking of how I would spend your savings🙂
