I think you need one other non-Skywalker, don't you?

If we arrange them so the each person 'gives' to the person below:

Luke1 Skywalker <luke / xxtheforce.net>
Toula Portokalos <toula / xxmanhunter.org>
Luke2 Skywalker <luke / xxtheforce.net>
Gus Portokalos <gus / xxweareallfruit.net>
Luke3 Skywalker <luke / xxtheforce.net>
Bruce Wayne <bruce / xximbatman.com>
Luke4 Skywalker <luke / xxtheforce.net>
Virgil Brigman <virgil / xxrigworkersunion.org>
Leia Skywalker <leia / xxtherebellion.org>

It all works until the end, when Leia is giving to Luke1.
(Otherwise, Leia doesn't give to anyone, and Luke1 receives from no 
one.)
