With the right feats, sort of.
Sword and Fist has a feat, "Monkey Grip" which lets you use (at a penalty) two-handed weapons in a single hand.
Theoretically, by taking hugely cumulative penalties, the feats Ambidexterity, Two Weapon Fighting, and Monkey Grip could allow you to wield not one, but TWO greatswords.
Some of my more munchkin-y "hmm, what'd happen if I did X" ideas center around those three feats, a pair of Keen falchions of speed, Imp2-Weapon, and the ImpCrit(Falchion) feat, among others. Threat range 12-20, 3 off-hand attacks and up to 5 primary-hand attacks, and semidecent damage to start with. VERY cheesy. 8) Also perfectly legal, unless I missed something huge in the errata.
