Why not just put a system in that roams?!?! Either ruckus or even luxul...
I get that we want to make a fun experiment and would be cool to break out a cat5 and run it through a relay but the novelty of it will ware out and you will never do it at a clients house.
I would use this opertunity to put in a controller based system to learn what works and doesn't with it.
Just my 2cents
