If you are an experienced Finish Carpenter, or a capable woodworker, almost anything can be done.
To tell you that it will be EASY would be greatly understating the possibility of you measuring wrong! It is HARD to get it right. (I have measured over 5,000 refacing jobs, so I have the hang of it now).
When a cabinet has a "FACE FRAME" and the doors overlay the face frame by 1/2" (or thereabouts), you decide what size to make the door based on the OPENING SIZE of the cabinet.
But, when planning on making a full overlay cabinet, you need to measure the full outside width of the cabinet and SUBTRACT a bit (like 1/4", 3/8" etc.). This complicates things SO much, particularly in corners. Drawers need to clear each other, so most will need to be remade in a smaller width from scratch. Door openings will need to be made smaller so the doors can have room for the hinges to mount.
It can be done, but it is best left to EXPERTS with plenty of measuring experience. There will be so many variables, that you will be nearly 100% guaranteed to be reordering several of the mismeasured doors.
That being said, here goes! :
"OVERLAY" MEANS 'HOW MUCH THE CABINET FRAMEWILL BECOVERED'. EACH DIFFERENT CONCEALED HINGE WILL FORCE THE DOOR TO COVER DIFFERENT AMOUNTS OF THE FRAME ON THE FRONT OF THE CABINET, ALSO CALLED THE "FACE FRAME".
A "900C" HINGE IS A 1/2" OVERLAY HINGE, SO THAT HINGE WILL FORCE THE DOOR TO COVER 1/2" OF THE CABINET FACE FRAME (on the hinge side). TO KEEP THINGS SYMMETRICAL, YOU SHOULD USUALLY ADD 1/2" TO THE HANDLE SIDE OF THE DOOR ALSO.
SO, BY MAKING THE DOOR 1" WIDER THAN THE CABINET OPENING, THE DOOR WILL 'OVERLAY' 1/2" ON THE HINGE SIDE AND 1/2" ON THE HANDLE SIDE WHEN USING THE "900C"(1/2" OVERLAY) HINGE.
IF YOU WOULD LIKE TO COVER MORE OF THE CABINET FRAME,YOU CAN ORDER A 3/4" OVERLAY HINGE, AND MAKE THE DOOR 1 1/2" BIGGER THAN THE OPENING SIZE.
REMEMBER, IF YOU WANT MORE 'OVERLAY' (COVERAGE OF THE FRONT FRAME), YOU NEED TO DO TWO THINGS:
1) USE A LARGER 'OVERLAY' HINGE...
2) MAKE THE DOOR WIDER. BY DOUBLING THE 'OVERLAY' OF THE HINGE, THE DOOR WILL COVER THE FRAME EVENLY ON BOTH SIDES.
THE "900V" HINGE WILL FORCE THE HINGED SIDE OF THE DOOR TO COVER THE FRAME BY 1 1/2" ON THE HINGE SIDE, SO THE DOOR WOULD LIKELY NEED TO BE MADE 3" BIGGER THAN THE OPENING TO KEEP IT SYMMETRICAL. YOU'LL WANT TO STAY AWAY FROM THESE HINGES UNLESS YOU COMPLETELY UNDERSTAND HOW THEY WORK, AND HOW MUCH OF THE FRAME THEY WILL ACTUALLY FORCE THE DOOR TO COVER.
