SX4 swap

Hello fellow Bhpians,
I need ur help. Everyone knows that the SX4’s head unit is beyond grieving. Let’s leave that alone. Is it possible to leave the head unit as it is and install a smaller units somewhere else? I know by doing this the steering controls will be lost but who cares. Is it also possible to retain the light in the head unit ( I mean make it look as if its functional) but run all the audio from the other proposed unit.
If some of you guys out there can do it or have figured it out long time ago then please help me.

Drive safe.
