Hello Squack,
According to several requests to Ming cycle and Strida Europe - no!
Due to the very special construction of the MK1 wheels (wheel does include the brake drum) it will not be posssible to modify any standard wheel, I’m afraid of.
Maybe you could speak to “inseq”, the poster of the thread below, perhaps you’ve got spare parts to exchange with him.

Good luck!
