Although drawing both image and border in one class would be a more efficient use of system resources, I think I've done something similar to what you're talking about, although not with NSImageViews.
If I understand you correctly, what you want to do is to be able to drag and drop an image without the NSImageView on top grabbing it. One thing you might be able to try is the setEditable:NO method on your imageview that draws the border. Then, it wouldn't be able to take the image that you drag to it, and the image may pass on to the ImageView below.
I actually had a view that sat on top of an NSImageView that drew a border using NSBezierPath, etc., and I was able to drag and drop things to it just fine.
