64 PDM MEMS--->XU232-1024---> &XLINK& --->XU208-256-QF48--->CORE_BOARD

I want to achieve 64 channels of microphone array audio sampling, with the sampling rate of 128 KHZ / 16 bit。my plane is : through XMOS chips to implement:
1、the preliminary idea is 64 product data management (PDM) data to a microphone into the XU232-1024 - FB374, complete PDM)to the PCM transformation;
2、and then through the X - link to transmit data to XU208-256 - QF48, converts the data to a USB data format, t
3、hrough BULK agreement passed to my core board do algorithm processing,

As above, please help me to evaluate the feasibility and risk, thank you very much
