A few on that list are worth including... but three completely different World XIs that would be just as good could easily be assembled:

Sehwag / Jayasuria / Smith
Gayle / Trescothick / Gibbs
Tendulkar / Ponting / Dravid+
Inzamam / Youhana / Clarke
Lara / Symonds / Pietersen
Sangakkara / Gilchrist / Shoaib Malik
Vettori / Warne / Giles
Vaas / Lee / Pathan
Ntini / Harmison /
Murali / McGrath / Naved-ul-Hasan

Somewhere in those four teams we should also have Attapattu and Collingwood: both absolutely world class ODI players.
