Yes. You can remove the old disk after the dd_rescue is done.

I believe vgcfgrestore does that. If you don't want to (or can't) move 
the disks around, check the -o option.

If you want to, you can use the LVM2 pvcreate instead, to create the new 
disk with the PVUUID from the old one. pvdisplay /dev/olddisk tells you 
the ID.
