...what's the ratio of distance between stud centers to thin piece
height in a LEGO brick? (Which is to say, if I wanted to build a
more-or-less perfect sphere out of LEGO... my own Death Star,
f'rinstance... what aspect ratio would I use?)

I'm not sure I can get this right, but I'll give it a shot...
If you want a perfect cube, you take a 2x2 brick, and top it with a 2x2
plate, and top THAT with a 2x2 tile. A standard brick is 3 plates high.
So a 2x2 brick is also 5 plates wide (if you exclude the top studs, and
they are usually inserted in something above them, so don't count. So I
would say that the aspect ration is 1 stud-to-stud to 2.5 thickness of
plates...
or...1 brick thickness is 1.2 to stud-to-stud ratio,
and...1 plate thickness is .4 to stud-to-stud ratio.
Does this get you any closer?

Well, I was bored one Sunday evening and rather than do some more Economics
study, I had a bash at working out the proportions of a classic 2x4 brick.
Would this help?
Taking a base unit as the thickness of a tile (I ignored the studs and
concentrated on the body of the bricks) a 2x4 brick is 3 tiles high, 5 wide
and 10 long. The gap in between studs is 1 tile, and each stud is more or
less 1.5 tiles wide. The thickness of the ABS is about 0.5 tiles.
I also worked out the thickness of plastic of the tubular bits on the
bottom, but I can't remember them!

Should be about 1/4 tile. More or less.

The basic ratio is 2:5, for stud-spacing to plate-height. Which is
why you see Technic models with beam-plate-plate-beam stacked up--this
allows beams to be placed vertically, and connected to the other
beams.
In LDU (LDraw units), the measurements are:
Brick height = 24
Plate height = 8
Stud pitch = 20
I believe the LU (LEGO Unit) measurements are:
Brick height = 6
Plate height = 2
Stud pitch = 5
... either of which will give you all the ratii you need.
