Looking at the way the Honda provided bumper on my SE is attached, seems like there would be a concern with mounting a winch higher - - that is, unless the bumper has higher up attach points. The stock bumper is mounted down low with the upper bumper tubes cantilevered up there in space, so to speak. Any pulling load, applied up high, wants to bend the attach points, frame etc., downward. Not saying it would do that, I haven't tested.
I'd be interested in learning how the aftermarket front bumpers attach, or how a higher mounted winch does.
