The DIB engine... does anyone know how to get it into Wine?

No then you don't have the engine yet. In my proposal you would first
make winex11.drv not depend on DIBs (the conversion code would still
be in winex11.drv), then you move the conversion code over (you would
still perform 8bit drawing using X by converting it to 24bit but this
conversion would be done inside gdi32). In the third step you would
add software based drawing functions, so the actual DIB engine.
