Anthony,
I agree about the repetitious nature of fw bunkers, whether its the RTJ or Dick Wilson "guard both sides of the LZ" to any number of nice outside the dogleg, beyond the LZ target bunkers, which I found myself too prone to several years back.
I penned a piece for Paul Daley basically asking "why?" Why, when there are so many viable and intersting bunker schemes a gca COULD use. I listed some, based on carrying, skirting, laying short of, one bunker patterns, and a variety of staggered multi-bunker schemes, and as you mention, a no bunkers scheme (bi-secting that into flat fw easy hole, and one where the slopes of some kind make up for no bunkers, etc.
I think I came up with over 30 "basic" ideas for bunkering a fw LZ, and it made me wonder why any course with 14 long holes would ever have the same one twice, excepting perhaps a cape style (or other strong concept where the land supported it) hole left and right to balance the challenges out.
I might fall into the Morrish trap, looking for a spot to do a bunkerless hole. I like to think I look first for holes that don't really need one, and suspect they do too, but that would be a matter of opinion.
I also don't mind a bunkerless green, but only if there is some compelling natural hazard or a man made substitute - like steep bank - which might actually be more punishing than a bunker in a similar location.
I will also say that when golfer surveys are done on my new courses where I used less or no bunkers in naturally beautiful areas with other hazard potential, the favorite holes always come back as the ones with more bunkers and average scenery. Golfers like bunkers, probably for looks. They do provide sharp contrast, as opposed to most of the day with shadows, or other subtler grass hazards.
