I've looked at doing this a couple of times. Some complications:

D3D12 doesn't use adapter_format_from_backbuffer_format().
The wined3d function turns message filtering on/off using wined3d_device.
No equivalent of 'swapchain->d3d_mode = actual_mode' exists in the D3D12 version.
The original window rect is always restored in DXGI but not wined3d.
The Alt+Enter handler in wined3d_hook_proc() calls wined3d_swapchain_set_fullscreen() too.

No doubt it can be made to work through a common helper with some optional parameters. It will probably be a bit messy though. It depends on what's more important.
