INA190: Multiplexing with Enable Feature

I am designing a current monitor using two INA190 chips: an A1 for low sensitivity, and an A5 for high sensitivity.  The user will be able to select one or the other using the chip ENABLE inputs to minimize current consumption. If the ENABLE pins are logically opposite, is it safe/advisable to tie the OUT signals together since only one will ever be enabled at a time?  Also, how about the REF input, since in this design both channels always use the same reference signal, can those be tied together?  This would greatly simplify the circuitry so that electronic switches are not required to separate the REF and OUT signals.
