I Like it. It's different from wormhole, because this happens automatically, not as an order.

Maybe it can be a wave that repeats itself every two years (one ripple after each S/F Season), and have a table like in Deluge. Maybe starting in the SW corner:
Ripple One: MAO, Spa, Por, NAf, WMe, Tun
Ripple Two: NAO, IRI, ECH, France, Italy, TYS, ION
Ripple Three: England, NWS, NTH, HEL, Bel, Hol, Germany, War, Austria, Ser, Gre, Alb, ADR, AEG
Ripple Four: Scandanavia, Bar, Bal, GoB, Fin, Ska, Russia - War, Rum, Bul, BLA, Turkey, EAS
The wave can go through, say, the top board first, and then the bottom board.

Or maybe there are 10 randomly selected spaces that get transferred if it is possible.

Or Each player chooses one opponent's piece to transfer if possible.

I like parallel universe better as a name...but then again, I am no physics major...
