Rob,
I have heard good players opine about similar problems. They (presumably right handers) always want the high side of any bunker to the outside of the fw. They dislike fw bunkers on the right that sit below the fwe, etc. On your dogleg, in essence, the high side is on the inside of the fw, causing the problem.
That said, and in combo with the tongue thread, I have thought about it over the years and really can't see how any bunker design other than a relatively flat oval might eliminate all lie problems, so I rarely worry about it. I have never done the old Robert Bruce Harris oval bunkers just to avoid the possibility of a sidehill lie.
It does remind me of an interview I had at a club, where they complained that if they hit a fw bunker on the par 5 18th, they couldn't get home in two. "Mr. Brauer, they asked, don't you think it should be just as easy for us to hit the green in two from that sand bunker as it is from the middle of the fw?" My answer of "no" didn't sit well with them. I did allow that it was a tight space, and the first renovation architect insisted on shapely bunkers in tight spaces, so each sand lobe was really too small to stand in, just because he wanted a certain look. I suggested we could simplify the shape, but somehow that also offended their sensibilities, but I didn't get the job anyway, for my "senseless" answer concering the hazard being a hazard. I even had elaborated that I thought it could be deeper, because if they hit it, they could go 9I, 9I and still hit the green in regulation, so there was really no penalty anyway.
