No. At least 256K flash required.

MicroPython runs on the L432 with 256k/64k. Have a look at it's linker script and mpconfigboard.h. You will see quite a few features turned off, eg pyblegacy, to make it fit. You might be able to have a 16k filesystem. There is room for 26k in L432 but I doubt you will get 32k. You will need 16k ram reserved for FScache leaving 48k. This is enough as F091 runs in 32k with 6k stack.
