The 0 14 fret is really that long? Darn. In terms of width dimensions, it isn't that far off from what you have there... but I guess the curves on the 0 are a bit different and lend to the longer body and scale. I still wonder if it'd work though.
Anyway, that body size you have there is more of less what I'm looking to create. It's a bit wider and a bit longer then the exact scaled down version of the 000 but that is just a template/idea anyway. It looks like, more or less, I'd want: Length: 17.5" Upper Bout: 10" Waist: 8" or 8.5" Lower Bout: 13.5" or 14" I think the length must be below 18" for the bridge to be placed well on the lower bout. I also think that increasing the lower bout size to 14" and waist to 8.5" might be a good idea. I don't think the upper bout needs to be changed... maybe bring it up to 10.25" or 10.5". I do wish the 0 size was right length... fixes needing to customize anything. But i'll have to see. I would likely keep with the Martin style X bracing though. I'd probably want it shifted forward to increase bass (plus might help with shorter scale and bridge being a bit further up than usual). Anyway, I appreciate the help and that guitar pattern was very helpful. To JonWint: the Little Martin is a bit smaller than what I want but the idea is the same. While I suppose the 23" scale on the Little Martin 15.75" body has the bridge at the "sweet spot" I think a slightly larger size that 90% of the 000 dictates would be better and still have the bridge in a good enough spot. I was hopeful the single 0 sizing would work but it might be a bit long. I still am considering it since I imagine the scale length will still work. But I will have to ask around and see. Thanks for all this help!

 You could push the sound hole down 1/2" and get 18 frets instead of 17... Doing it with an X brace scheme and pin bridge instead of ladder bracing and tailpiece would be trivial. But that's the guitar you are asking for in real life.

Yes, I know. I actually was reading those off essentially from your measurements.
I think even the Little Martin has 20 frets so perhaps there is a decent amount of room to move the hole down? I will have to look around for soundhole placement on the 000, 00, 0 shapes to get an idea. I hope that the X bracing would be trivial! Although I'm sure it's all gonna be tough, ha. I think what's really going to be important for me is to ensure the top is fairly thin and the bracing is also thin (1/4") and scalloped. The smaller soundboard will need the more responsive top for volume and bass. It seems "thin" for 000 and D sized guitars is about .105" or so from Martin. I was reading a long article (http://www.esomogyi.com/top_thickness.pdf) by Somogyi and it seems like you can even get down to 3/32 which is 0.09375". He also calculated out how much more thin a smaller guitar would need to be. It was interesting stuff. I'm definitely think for such a smaller guitar going with .1" or even .09 in thickness would be good. I also was hoping to use Engelmann which is a bit softer so I'm hoping all this together will make for a really nice sounding instrument. Anyway, again, thank you for this help. I have been reaching out and searching about kits and other ways to get what I need to build this. I'm considering some "local" classes that maybe could help. I definitely can't wait to make it a reality. The next stop after that might be an electric! But first things first, lol.
