Multiple airspeed sensors


I have the issue related to this topic. I understand that I cannot connect multiple sensors with same i2c addresses, and seems like I cannot use more than one airspeed sensor (because of calibration issues, and also if I connect two only one appears in the log and among the uORB topics).

Has anyone tried i2c multiplexer to get around this problem? I know I need a custom driver for it, but can it theoretically work? If anyone has any ideas or experience on multiplexers and px4, their help would be much appreciated.
