I wonder if apart of lvmcmdline.c above, also other parts of your software assume that sector size will always be 512. If yes, then I suggest rethinking if 4k sectors might break some operations in LVM. By the way, I understand that when specifying command line parameter sector size, then it is the same for small 's' as capital 'S', right? And the same goes for bytes ('b' is the same as 'B'), right?
