Sorry Partyrico, you're either wielding the two handed weapon or you have a hand free. Same as a fighter who took the deflect arrow feat.
However you can always use a free action to take your hand off the weapon. This means you have a hand free for Deflect Arrow, Crane Wing, and any other ability or feat requiring it. If you do so you're only holding the two handed weapon and not 'wielding' it. Limiting you're attack of opportunity to Unarmed Strike since monks can make these attacks even with full hands.
