If it's just straight up open voting on any team then won't SSK just win all the slots? They have a) the biggest fan base, and b) are sufficiently rabid that a huge proportion of them participate in such things.
I would have preferred each fan base gets to only vote for its own team. Then once each team's picks are selected they do another round where everyone must vote for players on a non-home team. That's the only way you fix the SSK numbers advantage.
Of course, with the way SSK is going this year, the fans are sufficiently miffed at their team that perhaps they won't vote for any player in green.
