Send info from MPU9250 with a ESP32

I have ordered a new compass sensor (MPU9250) to replace my old Raymarine fluxgate compass that never works properly.

Now, I got a problem with the distance from the sensor to my Raspberry(Openplotter) (>5meter) and was thinking maybe I could use a ESP32 to deliver the signals to the Raspberry instead of buying a I2C range extender. What do you think, is it possible? I found this page (https://github.com/natanaeljr/esp32-MPU-driver)

I have worked some with the sensors and used the ESP-32 and her little sister ESP-8266. However before starting to take the Internet of Things on Board (IoToB) I investigated in extending the I2C. This is a common problem and is solved easily. Use a simple I2C line driver chip. Take a look at my project : Yacht-server-with-raspberry and the I2C range extender . It might be that two small chips and two resistors and a 5m cable is simpler then using an ESP32 which also require power cable.

Good luck.
