If the user interface was good enough why not. Might need multiple devices to get enough screen real estate of course. I haven't kept up with PA tech, but I imagine it must be at or very close to a scenario where multicores are obsolete and all the kit stays on the stage except for the actual console, and that's connected via ip over w/lan, nothing physical. At my amateur/semi pro level that sounds like a major blessing just for setup and teardown in a cramped venue. The prospect of a teardown where there are nearly no cables on or off stage, and its just chuck all the kettle leads and extension leads in a box and load up would fill me with enthusiasm.
You know Jackson Browne had it right: the only time that seems too short is the time we get to play, and if the wasted time at each end of the gig can be reduced with tech I'm all for it.
