Moving config and params to second theme

Greetings,

I am working on a bundle of “features/capabilities” and am planning on bundling them as a theme, designed to be a second them to a primary one. (I think this in line with how modules are working). The features I am building require some parameters. How can I add to the available parameters in config/_default from a second theme?

thanks
