ATM design

I want to use Cisco 3660 for atm aggregation. Like I have two IMA 4 port E1 Port adapter modules in Cisco 3660. I also have ATM-OC3 modules in same chassis. I want to know is it possible with Cisco 3660 that I can use it to make cross connect between multiple IMA interfaces and OC3 interface in single chassis.
