FWIW, The Stateless Society (me) doesn't make quilts anymore, and the Cyanocitta was a special style I only made a few of for TiGoat and a few customs.
What someone mentioned about not buying a hammock quilt for ground sleeping is true. Honestly many (most) quilts even made for ground sleepers are too narrow, unless they're contoured and have a system to retain the quilt around the body like the Katabatic designs. The more contoured however, the less "versatility" in sleep style however.
Since I recently started using inflatable pads, I've realized that for a flat quilt to drape properly and not require constant adjustment, you need even *more* width than I realized, since the thicker pads sides encourage drafting when the quilt hangs down off those sides instead of laying down on a ccf pad or the ground around it.
Since someone mentioned Warbonnet (yes they are a hammock company) I had a chance to handle one of their quilts when Chris W. was doing an article on quilts a year or two ago, and I have to say it, and the Katabatics were the ones that stood out to me as having the best workmanship.
If you got them to make you a quilt to your height requirements with the same width as their "wide" top quilt, I think you'd be very happy with it for 3-season use.
For winter, the more I spend out on winter trips, the more i realize that a standard flat quilt without some advanced draft protection is just a horrible night's sleep waiting to happen. If you're a back sleeper, a Katabatic style quilt is probably an exception to this when utilizing the rigging, but I'm of the opinion that below 20 deg a flat bodied quilt starts to be seriously inefficient.
I did make some models (like the cyanocitta) that to greater or lesser degree alleviated this issue, but I never settled on a design I was 100% happy with, especially once dealing with 10 degree F or colder temps.
Hammocks are an exception to this rule however, since the hammock bodies tend to keep the quilt neatly on top of your body no matter how you lay, and need much less width because of that. I'm confident that with adequate bottom insulation, you could take a hammock to any reasonable temp desirable.
