Or connect the 2 mirror ports and a single NIC sensor to a hub (doesn't
sound optimal)?

If the mirror ports are unbuffered (like most taps are), you will be
loosing packets due to collisions on the hub. You should connect the
taps to a switch instead and configure the switch such that you dedicate
a monitor port to receive packets from both input ports. Then connect
Snort to the monitor port.
