Here's my 7x7 spiral starcase design (9x9 if you include the outer walls).
Overhead view:
W = outer wall
1, 2, 3, 4 are landings
S = stairs
(space) = open - mine it out or don't at your preference.
X = floorblocks in horizontal views.

Start with a 2x2x2 landing. Dig a 2x2 tunnel forward 5 squares (landing is now 2x7x2). Remove floor 2x5x1, then floor 2x4x1 then floor 2x3x1. Notice the lower landing is 2x3 before stairs are added.
Here's a side view before stairs are added.

Now with stairs added, the lower landing is 2x2

Turn 90 degrees and repeat until bedrock.
In my version, I place torches on the floor in corners, I mine the 8 squares around the center, but leave a single block central pillar in the middle from top to bottom.
In the original version, I started at two opposite corners and made a double spiral staircase. While this does find all the minerals, it's a lot of extra work. I had hoped in the future to improve the design to allow a waterslide down one, and a minecart ride up the other.
Pretty sure you can't do this without using a world editing program. Just have your wife join, teleport her, and have her sleep in a bed.
You can teleport like this:
/tp [wife's username] [your username]

You can always use a command block with the following setup:
Replace
<name>with your name, obviously.If you want to do this with all users on a single world, use the following command:
Make sure you turn off command block output, though, and also make sure you put this block in a permanently loaded chunk (your spawn chunks, for example). You may wish to use a setup involving repeaters instead of a repeating command block (as repeating command blocks act very quickly, and may cause lag). I'd generally suggest against doing this, however, because you don't prevent yourself from dying in a loop (which is not only possible, but probable in this).
