What you propose sounds very interesting but I'm not sure it's obtainable or will do what you intend. You will have to excuse the cynicism expressed here because the spoke wrench and wheel truing have been around for well over 100 years and, if there were a significantly better or easier way to do it, particularly an affordable one, we're pretty sure it would have been developed by now. That's not to say it may not be possible but I, for one, won't put too much of my own money on that bet.
