Hi, is it possible to plug a wifi adapter bridge on the Ethernet port of a Duet Ethernet?

Hi, im looking forward to upgrade my Tevo Black Widow with a Duet Wifi, but before that i just want to ensure what i will need to make work,
Will it be just "plug & play" or i will need to make some configurations?

Printers PSU outputs 24V, and it powers up 2x 12cm fans for the electronics case, 1x extruder E3d with its own fan & 2 blowers, the current main board and one mosfet for the bed.

My questions are:
1. will it work with the stock endstop sensor
2. with stock motors
3. with the mosfet
4. with the display controller with the SD card reader (i know that Duet has micro SD slot on it but wonder if i can use the current SD card reader of the display controller or to extend the duet SD card reader cause it doesn't seems to be practical for easy access).
5. ?maybe i forgot something

I understand after installing the duet board i will need to calibrate the hotend, feeder, all axis and etc. but what about the firmware?

If anyone has already use it on a Black Widow let me know by sharing a few tips and the experience through the installation and after.

Thank you in advance
