So the idea itself seems good to you AND that's enough for me as well.

And about the next part, you will.
Consider a situation that you're going to develop a client or something in
embedded or desktop and you don't need to deal with QML or something else
for your modern interfaces, and just wanna keep going with C++ then
MaterialWidgets is a good option.
