I have a VS980, and I have flashed most of the ROMs available in the dev section for it. I don't believe that any AOSP-based ROM is going to have knock-off, so you would have to use one of the stock based (such as Malladus or XDABBEB). These in general aren't going to have minimalist look of AOSP based ROMs though.
Your other choice is to run an AOSP ROM with Xposed. I know that the Xposed GEL Settings module has an option to set double-tap to an action, though that may be a premium feature you have to donate to receive (which I recommend anyway, as it is an amazing module).
