A pretty good idea. There is subset of this that's worth messing around with called "Guide Tones" in jazz improv. Usually, they are considered to be the 7th and the 3rd of the chord, but can be any of the augmentations as well to a lesser degree. They add tension at the chord change. If you play a root or a 5th, it heads toward a resolution. Then, there's jumping the chord change which is playing a note in the chord just before the chord. Many jazz riffs start off the beat.When the chord changes, play a note that's in the new chord.
Along with modes, all these things are just tools in your arsenal. They are worth knowing, but not worth getting hung about. If messing around with these things pushes you out of your box, then they're worth exploring. I was exploring modes within the context of chord positions a couple of years ago, so that I'd develop a natural association between fingering patterns and chord shapes. That turned out to be really beneficial when riffing regardless of the type of music.
I was reading an interview with Alex Lifeson recently and someone asked him about scales, he said that he didn't even think about them when composing a solo.
