cisco 1841 t1 bonding

Hello I have pair of Cisco 1841 routers currently connected via HDLC over a serial 1t v.35 to an addtran csu/dsu on a T1 line. The addtran is providing 1/2 of the T1 line to our phone system, and the rest to the 1841 for data.

This was not enough bandwidth for our application so I ordered an additional  T1 point to point and two new t1 WICs for the routers.  

Is there a way to "bond" the existing serial 1t wics with the new t1 wics to get the bandwidth of the current 1/2 T1 plus the full bandwidth of the new T1?
Thanks
