You can use vgreduce and vgextend to reorganize Alternate links.
vgreduce /dev/vg11 /dev/dsk/c19t0d2
vgextend /dev/vg11 /dev/dsk/c19t0d2
and vg11 will become to:
PV Name /dev/dsk/c13t0d2
PV Name /dev/dsk/c18t0d2 Alternate Link
PV Name /dev/dsk/c15t0d2 Alternate Link
PV Name /dev/dsk/c19t0d2 Alternate Link
One thing I don't understand is that why you expect the "Total PE" will be reduced from 6945 to 5208?

Re: Change PV Link path
Yes either you can do vgreduce and then vgextend or try this single command
pvchange -s /dev/dsk/c13t0d2
this will set the /dev/dsk/c13t0d2 as the primary disk
pvchange -s /dev/dsk/c13t0d2
this will set the /dev/dsk/c13t0d2 as the primary disk
