The Catweasel floppy can not be used as DF0: in WinUAE period. WinUAE provides emulation that allows you to mount the floppy as CAT: using multidisk.device on the Amiga side (same as Z2 Catweasels). Adding a Kylwalda to the mix will not help this limitation.
BTW, ADF can be NDOS. (You're probably thinking copy protection, for that it's best to use CAPS/SPS images.)
