Bump-n-Run and the others had good ideas.
The gap wedge should have a smaller bounce 6 - 8 and the SW (56) 10 to 14 depending on your taste. The larger bounce will make a diffence in the sand traps we never fall into.
I am not big on bending but the GW of 52 is within the 5 degree step which I have read is recommended. That makes the 56 four degrees away so bending them a degree or two may be helpful. I get the same effect opening the face but to each his own.
