I wonder if a blank plate would fit over a control4 light switch if you left the buttons off of it?

I'm pretty sure a controllable switch will fit in single gang box. Forget the blank plate, that looks more like a mistake than a planned feature. If you have to hide it above a shelf in a closet somewhere. Don't let the architect dictate this feature. The initial solution sound more complicate and less robust than just adding a switch.

If you can sell a whole house C4 system, I's sure you can work around this guy!

Niles, Russound and others have made them in the past. I used them years ago to control CD players with hard power buttons.

We have used something similar to this in the past to switch an Exhaust fan in an equipment closet with a Crestron system.

There is no work around with separating the high and low voltages, and 95% of electrical inspectors understand this limitation and will pass the inspection because there is no work around. If you want to, give your local inspector a call and ask them how to do this to code, I will bet they can't find an answer for you.

For you that are saying it is against code how do you work around a security system smoke alarm relay as you have high and low voltage connections in the same box?
You can't fix stupid

You don't.
We had a lengthy discussion about his few years ago.
You can break the law and do it, or use dual systems,line voltage and low voltage detectors side by side.
Kiddie or someone made one for a while that was UL approved, but I don't remember what happened to them.

Use model PAM-4. Make your low-voltage connection outside of the one-gang box.

These are UL listed.

The NEC provides the specific rules governing Class 2 conductors and electric light and power conductors within the same wallbox. It states that electric light and power conductors may be allowed in the same enclosure as Class 2 circuit conductors, provided they are both introduced for connection to the same equipment, and if one of the following requirements is also met:

1) The electric light and power conductors are routed to maintain a minimum of 1/4 inch of separation from the Class 2 circuit conductors. 

Or:

2) The circuit conductors operate at 150 volts or less, and meet the following requirement: Class 2 circuits are installed using types CL3, CL3R, CL3P or permitted substitute cables and the cable conductors extending beyond the jacket are separated by a minimum of 1/4 inch, or by a nonconductive sleeve/barrier, from all other conductors.

Your local city, county or state authorities could have different or additional codes.
