I would (and do) pay for this type of UI library. Especially in design, everyone is inspired by everyone else, taking inspiration and ideas from elsewhere is normal... but branding this as "reverse engineered" makes it sound stolen. From the comments, it seems like you're actually just inspired by the work of others, as you've apparently written the code from the ground up, which means you're talented and capable. You should change the branding. Even a name change to something as simple as "Inspired UI" would be a meaningful improvement. I'd like to buy this but I'm not paying for stolen code, and as it's branded now, it seems like stolen code, and I'd have no plausible deniability if it turns out to be stolen code.
