Multiple devices on I2C extenders

I have two sensors that I need to place about 10-15 meters from my Raspberry-pi.
I am planning to use 2 sets of these distance extenders:

P82B715TD Long Distance I2C Bus Extender I2C Mini Module
https://store.ncd.io/product/p82b715td-long-distance-i2c-bus-extender-i2c-mini-module/

What is the best way to “split” the I2C port at the Raspi to feed each of these (since these do not have through ports). Planning to use this adapter:
I2C Shield for Raspberry Pi 3 & Pi2 with Inward Facing I2C Port
but need two ports.

I saw this multiplexer:
TCA9546A 4-Channel I2C Bus Multiplexer

But that seems like over kill, and I don’t need them on the same address.
Could I just stack two Raspi Inward Facing I2C Port adapters?

Thanks!

You can just stack the adapters as long as the sensors don’t share the same address.
