Since you didn't give the OS version I would say no… but not quite…
if all can be brought back to one disk, then you could vgreduce, add the new disk,vgextend etc… but you will get caught by max PP per pv… I know there was no (official) solution under 11.11 but if you knew well HP support team you could have got vgmodify command but its was still limited, thoughI did this a few times I never went on add something more than 3-4 times the original size, it was mostly replacing in L classes the 18GB by 36 GB disks… now I know the command was included in later release but which? I don't remember sit sure 11.31 has it

NAME
pvck - check physical volume metadata SYNOPSIS
pvck [-d|--debug] [-h|--help] [-v|--verbose] [--labelsector] PhysicalVolume [PhysicalVolume...] DESCRIPTION
pvck checks physical volume LVM metadata for consistency. OPTIONS
See lvm for common options. --labelsector sector By default, 4 sectors of PhysicalVolume are scanned for an LVM label, starting at sector 0. This parameter allows you to specify a different starting sector for the scan and is useful for recovery situations. For example, suppose the partition table is corrupted or lost on /dev/sda, but you suspect there was an LVM partition at approximately 100 MB. This area of the disk may be scanned by using the --labelsector parameter with a value of 204800 (100 * 1024 * 1024 / 512 = 204800): pvck --labelsector 204800 /dev/sda Note that a script can be used with --labelsector to automate the process of finding LVM labels.
