2*2 MIMO setup

Hello,

Iam interested in implementing a MIMO 2*2 scenario where i will use 2 fpgas (1 as the transmitter and 1 as the receiver) where each one  will be connected with one AD-FMCOMMS3-EBZ.
So the setup will be :
FPGA_1 + AD-FMCOMMS3-EBZ_1 =Base station  ,  FPGA_2 + AD-FMCOMMS3-EBZ_2 = User Equipment

My questions are the following:
1)Is this doable?

2)Is it better to use one AD-FMCOMMS5-EBZ and implement both the transmitter and the receiver in one FPGA?

Thank you

Manos
