Xiaomi wireless switch in wall switch home

Hi to everyone,

Well i have an idea that maybe someone can help me.

I already have simon 75 wall switch at home, and in place where i don’t have e27 bulbs, i thinking to put a wireless wall switch like xiaomi one.

The problem is that each device of xiaomi has a high price (around $43), and the configuring switches at home will be broke if i put this device (places where i have 2 or 3 switches).

So the idea is using a xiaomi wireless switch that have a price around $9, open it and make some DIY to insert in the simon 75 wall switch.

So the questions are:

Someone saw a xioami wireless switch inside?

Can someone think that this is possible to do it?

thanks
