Or gone back to a year before the Angels started popping up, and just wait for Amy & Rory to appear.
Or pop back to that time, but in a different place. Take a plane/train/whatever to get to NY, pick up the Ponds, then get back to the TARDIS.
There is, however, one thing I can think of that allows their predicament to make any sense: Rory killed himself b/c the Angels would always keep coming after him. The Doctor couldn't get the Ponds out b/c the angels would come after them no matter where & when they were. (Which... is also terribly wonky.)
