Filing Personal Property Tax under spouse when bills are in your name.

Since my deduction cap is set at $5k when filing 'married but separately' (we need to file this way) and I hit this limit with mortgage interest alone, would it be okay to move the personal property deductions to my wife's filing? The personal property tax is in my name since all the car  titles and house are in my name (I purchased them all prior to marriage) but since we are married I'd consider them expenses shared by the house hold.
