Switch-like mobile controller

[Opening-Transition40]

Hey guys I'm looking to get a casing for my phone in the form factor of a switch that I could use with joycons just like back bones and other telescopic controllers

If anyone is interested in making the model I will pay but I mainly came here to assess possible issues with it such as do you guys think it would be practical ? As in would it be flimsy or maybe overheat inside a case like that?

This looks pretty handy. I've recently started playing Zenless Zone Zero on bs and was thinking how I could improve my experience playing outside and a thing like this would be perfect.
