Why do you need to shuffle?

fdisk /dev/sda
delete the PV partition
create a new PV partition starting at the same sector but ending at the end of
the now larger disk.
write it out and reboot.  I forget whether the reboot is still necessary, but
I think fdisk will warn you it is if you've got mounted filesystems on that
disk.
pvresize /dev/sda1

Done.

I see no problem with #2 though.
