Nice idea. The issue with the idea is shown in the lower video in the link. While they keep the bags from folding in towards the wheel, they don't keep the bags away from the bodywork up top. More importantly they don't provide any standoff at the top, so the bags in the bottom video are being held away from the bike by the turn signals. I''m sure that's gonna work well....I like the looks of these -

Simple and not much hardware left hanging on the bike when the bags are removed.
OP has a Z1000 which means no grab rails and a more waspish tail than the Ninja 1000.It might be an issue the the Sw-Mototech bags. The grab rails on the Ninja provide some outward spacing but the turn signals stick out farther still. The FastRack would probably fix the problem, or shorter turn signals.
