We have a similar problem within the KDE project, 
As we have an entire desktop environment whose entire styling depends on 
QStyle, continuing to use QStyle to theme desktop apps, at least on a limited 
extent is vital.
As there doesn't seem to be interest in the upstream project in such a thing,
I started writing a QtQuickControls2 style that actually uses the very same 
StyleItem used internally in QtQuickControls1, it can be checked out at:
https://quickgit.kde.org/?p=scratch%2Fmart%2Fdesktopqqc2style.git

to be installed and then export QT_QUICK_CONTROLS_STYLE=Desktop (probably i'll 
have to rename it to avoid possible future conflicts with upstream ones)

Even if is still incomplete (and are things that unfortunately can't be fully 
styled yet in a fully desktop friendly way) it seems to work remarkably well.
