Whatever floats your boat I suppose. If you keep up with trends you will see that the "smart house" concept never really took off so I wouldn't expect too many people to be interested in your version even if they were willing to pay the price.
Another point is that your design may make perfect sense to you but as professionals we have to realize that at some point we will be out of the picture and somebody else will have to figure out what we have done. If we reinvent the wheel nobody is going to want to service it which leads to angry customers and eventually the system being abandoned.
