I'd like to het my wife a new set of wheels but her rear spacing is 126mm.

Can I buy a new set of 130mm wheels (Easton Vistas) and respace them?

nope, but you can respace the frame if its steel. or just bend it out a bit while you are installing the wheel.

BTW: boutique wheels are a scam.

Yes,
You can get thinner cone lock nuts.
You can also change the axle spacer size but this will require re-dishing.

Just open the rear triangle a little by hand and put the wheel in, it will fit tightly but it will fit. Unless you need to do lightening quick wheel changes during a race, this will work fine.

Problem: your wheel is spaced 4mm wider than the frame.
Solution 1: spread the frame 2mm on each side at the rear dropouts
Solution 2: remove a 4mm worth of washers from the non-drive-side of the rear axle

Respacing the wheel will increase the amount of dish in the wheel (referring to the disproportionate load borne by the drive-side spokes), and is a bad idea if it's an 8-speed (or more) wheel. 7-speed wheels come with 126mm and 130mm spacing, and it's fine to respace a 130mm 7-speed rear hub down to 126mm.

Respacing the frame is easy with a steel frame. You can either stretch the frame's dropouts apart each time you remove and install the wheel, or you can permanently alter the frame by spreading (http://www.sheldonbrown.com/frame-spacing.html) it.
