I do a lot of remodeling also and unforunately it's the nature of the beast.
My best relief has been using stranded wire, especially for GFCIs with 12 ga wire. The increased flexibility of the wire makes it much easier to install the devices. Also, if you're installing two devices, sometimes you can use a 4"x4" box with a mud-ring. This gives many options for depth that will give PLENTY of space. The boxes (without brackets) can be mounted beside a stud with wood screws through the box. If you gang a 4x4 with a 4x4 extension and a 1/2" ring (total of 3.5" deep) you'll be in space heaven!
With a little luck and care a double cover will just cover the hole. I usually warn the homeowner that some paint touch-ups may be needed (I even patch the ring). Hope this helps.
