While there's nothing wrong with attempting to match the termination Z, don't assume that it will do much. The input Z of the RX may not be 50 ohms (although the doc may say it is), a small mismatch won't contribute enough loss to matter, and it does not affect noise rejection. What matters is balance and twisting.
