Even though it is off topic, you are wrong. Chukanova in 2002 was backup setter to Gracheva and in some matches replaced Plotnikova for short times as opposite, but all she did there was receive some balls and set when Gracheva defended, but she never played like an attacker. In 2003 when Gracheva retired and Sheshenina was still too young, Chukanova became first setter, but she really was not good so as soon as Sheshenina reached a good level Chukanova was back on bench.
Anyway, if Wensink is talented to play as setter I see no reason not to try it.
Aha. I saw her first here http://www.youtube.com/watch?v=rh1nbKvcM28&feature=related and she was playing there as a OH. It's really unconventional, but always some way.
