Hey Chris,
This is intersting material, and the type of material that turns into killer bonsai. Yes the coils need to be brought in a bit but not much at all.If anything I would take some of the roundness from the bends and make them tighter more angular. If it were mine I would plant it in the ground for a few years to thicken it a bit but to also get a big jumpstart on the bark production. I think if you let a single leader grow wild for 2 years then spent 3 years needle plucking and working on back budding you would have a kick butt tree. You can do this and still work on bark production while keeping it in check for the last 3 years.
What I noticed in your 3 pictures was a junk trunk, a nice trunk and an ok trunk. To me, I think the trunk is the most dynamic in the 2nd picture but would really like to see a picture of it inbetween the 2nd and 3rd pic for a possible front. In one of the pictures I noticed a fair amount of wire bite in that looks to have caused reverse taper near the top of the twists. I would graft a scion at the base of that swelling and create the new tree from that point.
A shohin, with good bark, good trunk movement, good nebari and something that you won't see everyday. I also attached a tree I found while searching the net that could prove to be a bit of inspiration and very certainly doable given what you are starting with. Serious, you have what could be a killer tree here if you take the right steps with it.
The picture I drew on has a blue dot that is located about where I would graft on it and then another possible idea.
hmmm.....allrighty then.
Take the view in the first picture, lay the tree down on the ground to the left, then there is a possibility that could be very interesting.

That would make it a corkscrew with trunks 2 trunks comin off it. hmm......
