Yeah you could do it. One of the theatres I work in has the box that you plug in via a multi pin plug. Them has a toggleswitch for each led. I've never got to explore how it works but the must be a power supply somewhere and and the box interrupts the live wire
You could always use a micro controller such as an arduino and use its outputs to interface led's and different push button inputs, this would also allow you to add midi control and cue from some form of show control software if needed
Decide what features you need first: quantity, presets, response, etc. A lot want a relay station as well so it can power more than an LED. Then decide if its worth building.
It's a cool idea, but the last thing I want is for my stagehands to have an excuse to be looking at their phones backstage.... also if you're standing by to pull a rope how exactly can you hold your cuephonelight?

for out latest show we used the Intercom Cans Signal lamp for our StageClear LX up cue
it worked quite good but that means we can only control one cue light.
