AM26C32 Fail-safe circuitry

Our customer has a question about AM26C32.
I'm posting the questions for a customer:

++++++++++++++++++++++++++++++++++++++++++++++

AM26C32 has Fail-safe circuit in case the inputs are open.
When the Fail-Safe circuit is working, the outputs always are High.

But we need that the outputs are low in case the inputs are open.
So, connecting input A to GND and connecting input B to VCC
with series resistors(10k-47Kohm) will make the output Low.

Is this idea good?
If the idea has problems of differential data transmission,
please tell us what to do.

thanks in advance
