'Meroke' is never possible Ken, that's a yellow one. In my opinion it's a 'Graciosa' aka 'Loenik' It's a Dutch mutation found on a 'Nana Gracilis'.

Certain Old World origin references appear to show and describe a different plant from what is sold as 'Gracilis' here. Plant shown on this thread isn't necessarily "our" 'Gracilis', there are a lot of different Hinoki being grown. And it has more fluffy, less flattened sprays than I would expect from 'Gracilis', which I have been growing since the 1960s. However, this feature could of course be present on some specimens and not so much on others due to cultivariance etc., and I have not looked at mine to be sure it is different while composing this post.

No idea but the color is beautiful. What kind of scent does it have?

Impressive amount of thought and work going into this ... I will enjoy looking into what you are proposing; until I can, I wanted to throw another option to you just because of the general look of it (there are so many out there, that is part of the joy). I have a "Sherwood Frost" arborvitae that is very slow growing, and tops out at about ten feet. It is a wider pyramidal shape, but is definitely NOT deer-proof. Perhaps part of what you like about the aesthetics of the chamy obtusa is the architectural way that their fronds splay and twist a bit. It is definitely suited as a specimen focal point. I actually believe mine failed because I had them in very sandy soil. They became thinned out with interior browning instead of the full look that I was going for (as a hedge). However, few chamaecyparis will take soil that is too moist. I did have one in the blueish family that actually liked a wet soil (will have to look back to see what sub-species it was). If you continue to look hard enough, you will find what you want! http://woodyplants.nres.uiuc.edu/plant/thuocsf
