Has anybody thought about incorporating some sort of wire in 120V to 3V regulator to power the sensors?

Yes done it on several sensors including the one connected to my smokes:

Make a battery powered sensor run on USB

I have a few sensors in locations near a receptacle but yet I continue to change batteries. Well no more! After reviewing several YouTube videos and doing a little research I found a small device a little smaller than a CR2 battery that converts 4-12V DC down to 3.3V DC which is the equivalent to 1 CR2 or 2 AAA batteries. I converted my first sensor today and thought I would share. Here is a good video tutorial. I ended up getting a slightly different power module than the one mentioned in the video since this one has a higher range of input voltage. Plus it is smaller in size too.
