The Hutchinsons look great in my opinion and have a deep backspacing. I was hoping to run them without spacers and that is how they are in the picture you posted. I did run them on my 80 series with Toyo 37s, and didn't have any significant rubbing issues that I recall. The 45 body is obviously different but hopefully you could run them without spacers. The Hutchinsons are really heavy but after trying to dismount tires from them I feel confident I won't loose a bead unless I destroy the rim.
Those Walker Evan beadlocks look good too, on the 45 you posted and Project X - both 45 builds.
I think the 17" fj steel rims could look good too. I have plan to eventually build a set to mount acorn hub caps on. I am still waiting to see how they turn out before I decide how I feel about them.
I have not really looked around for examples but I think some of the method rims might look good on a 45. They have a couple new ideas with different bead retention options available now that are not as obvious the bolt on ring style.
