Or maybe "just" use a new, chromeless frame. Anyway, I'd expect some C 
code to have to be written for that feature.

Without new frame, we also won't be able to make Company tooltip work in 
minibuffer, Maybe we can adapt by rendering it in the nearest window, 
but that will leave a somewhat hackish impression, even if it works well.
