theres a few problems here
asuming you are trying to reverse the doors through 180 degrees
assuming the doors are suitable you have to concider so many other
things you have a9degree splay [slope on the bottom of the door]
you turn them round you loose about 18 mm
the overlap on the doors would still mean the same door will open
first but you will now have to open handle on what is now the
other door
if the doors where shot in [fitted] and where slightly out of square
this problem would now be doubled
so as masona said
