When you add the LV copy and synchronise them, the image of the PP is copied irrespective of what it contains or doesn't. I'm afraid you will just have to wait.
It doesn't matter if you use mirrorvg or mklvcopy. It has to copy everything. Use:-
... to see how you are getting on. This may get locked out if you are running mirrorvg in the default auto-sync mode. You can ease this by running mirrorvg with the -s (lower case S) flag. This will create the LV copies and then you can synchronise them with syncvg -v yourvg
Make sure when you remove the LV copy, that you specify the hdisk to remove the copy from, else it may well just pick the newly created one.
Caution
Do not interrupt these processes else the ODM and the VG disk information may get out of step leaving you unable to complete the sync. There is a way out, but it's a bit messy.
I hope that this helps,
