You say Jimi blended blues and psychedelia. EVH blended rock and virtuoso jazz/classical lines--what's your point? Hell, eruption's tapping part is taken straight from Vivaldi. I would think that blues and psychedelia are easier to combine than virtuoso stylings and rock. Not only that, but EVH also took the whammy bar to insane extremes. Sure, Jimi divebombed every now and again, but Eddie is the one who really made it happen in terms of whammy effects. And he also helped design the Floyd Rose.
Again, Jimi also wasn't the first to play very loudly either. A lot of his contemporaries were experimenting with similar things. The same thing you used to dismiss Van Halen can be applied to Hendrix---he was more commercial ready and bombastic than others who were equally talented than he was.
EVH also played a strat, it was just a modified one. Jimi didn't have the same impact upon guitar design and whatnot that Eddie did, either.
Back In Black isn't a song. It's a divine call that gets channeled through five righteous dudes every thousand years or so. That's why dragons and sea monsters don't exist anymore.
