IMHO, the 100 WR macro is a lot of money to invest in a specialized lens unless you're going to use it extensively. I own it myself, but it's hands down my most used lens ( when there isn't snow on the ground ) and it has paid for itself. I don't really use it as a macro lens per se ( I almost never go down to 1:1 ), but I sometimes get down around 1:2. I would think that for the average person who only does occasional closeup/macro, it's probably overkill. Of course, it's also a good short tele lens. If you decide you want a dedicated macro lens at some point, you could get an older 100mm F4 macro for a fraction of the cost. Even a used DFA 100 macro should be a fair bit cheaper than a new 100 WR. Or maybe a 50mm macro would be better - depends on what you intend to shoot with it.
I only do day hiking, and I'm very conscious of how many lenses I carry. If I was doing a multi-day backpacking trip in the wilderness, I'd be even more leery about carrying too many lenses. But maybe your back is stronger than mine
I've never used anything like the Raynox, but I don't see why you couldn't put it on your 18-135.

I never owned a really wide angle lens until this year when I bought the DA 15 in December and started shooting with it in January. It is quite different. For years I didn't know what I was missing. I always shot landscapes with telephotos - that was my norm - and many were great - but that's not a reason to say you should use that as the normal choice for wide vistas. My time shooting landscapes with Tele's was mostly during film era so there were no stitching options worth thinking about. Now it may be possible to get the perspective of the DA 15 without the dedicated lens. I have trouble visualizing this perspective without the lens in hand - I haven't developed an eye for stitching yet.
There are some interesting panorama examples in this thread:

I'm not sure you could get the exact same perspective as the 15mm lens by stitching images shot at a different focal length, but you could capture a similar vista. You would be shooting at a shorter focal length, so the effect would be different. Depending on what lens you use, you could potentially have fewer problems with field curvature and distortion, and you could certainly get a wider aspect ratio, but you're stitching together multiple photos so their could be artifacts.
I wasn't suggesting pano as a substitute for the 15 LTD - from everything I've heard it's a great lens. The OP wants to cover a lot of bases, but can only afford to buy and carry a few lenses. If he wants a long zoom for wildlife, then he will likely have to forego the WA prime. Stitching pano's together from shots taken with his shorter zoom is a "next best" option to having the WA prime.
