I think a modified fence could serve well as a bunker. Here's another example at 50:00:
The result would be better with fences designed specifically for a given hole- various heights, lengths, shapes and slat configurations. The fence wouldn't completely obstruct certain putts, but it would make them more difficult by forcing shots to go over, through, around or under. Shaped hedges could serve the same purpose, but maintenance would be greater and discs would get lodged.
