If you write a small http mbtiles server then you can use one of the existing plugins that are bundled with Qt. I’ve done this using the mapboxgl-plugin. You can run the “server” from a thread in your application if you want. This might be the easiest solution for you, sounds like you have most of it already. For the mapbox-gl plugin, pass it an additional style to use, then serve this style from your server. You must also serve a “tilejson” file. Check out tileserver-gl on github for inspiration (node.js-based).
