Option for themed taskbar buttons on Windows 10

Not exactly sure if it's possible to apply to the Windows 10 taskbar, but it would cool if there was an option to apply the theming to the buttons.
Thinking of something along the lines of SetWindowTheme(hwnd, L"TaskBar::Toolbar", L"Toolbar"), if it's possible to get the handles and set the themes of them of course.

I'm personally using a Win 7 theme and even faked my taskbar by making it transparent and putting a aero styled one on the background image, but these flat buttons still bother me. 7+ Taskbar Tweaker was already a big help and this would be pretty cool imo.
