Replace the Kintex 7 XC7K70T with XC7K160T on the Skoll Kintex 7 FPGA Module

I just wondering if we can replace the Kintex 7 XC7K70T with XC7K160T on the Skoll Kintex 7 FPGA Module? It seems the XC7K160T and XC7K70T have the same package. But I am not quite sure if we can do a simple replacement.

Also, can we get the schematic/layout of this module if we buy it?
