Well, I’m not exactly the expert on this stuff, so don’t blame it on me if it is wrong. But, I heard from one of my friends that in order to take stacks off, you have to take out the whole bearing/axle system or whatever. So I guess it is possible, but I’m not sure really. Hope I helped anyway bye bye
Looking at it (in real life, of couse), I would highly doubt it. The rings seem to take up too much space, and I don’t think the Z-Stacks would have room to spin.
