Do I need customization for bootstrap?

In my projects I often use bootstrap. He's great. And in order to make it even more universal, I had the idea to make a service for its customization. Before, of course, I looked for analogues and was pleasantly surprised by the abundance of resources using bootstrap. There are collections of finished topics. I found a service that allows you to seriously change the appearance of bootstrap. But it is a little overloaded with details and in order to create a convenient version of the theme, I must have prepared color palettes. Cool, but not very usable as for me. So I decided to concoct my service with a convenient and simple interface that would give the user an archive of the latest version of bootstrap with the saved color scheme.
But I don’t know if this idea will be interesting to people. And I want to make a thing useful and necessary for people. Therefore, before diving into coding, I collected a small prototype that simulates the work of a future service. There are only two elements in it.
Are you interested in such a service, or is it? ..
