I wouldnt expect visualizing to do anything for your playing.
Transcribing, Composing, etc. will though.
The only thing I've heard of like that is in martial arts where
they imitate the fighting techniques and/or spirit of animials.
In composition, sometimes people try and use music to create a variety
of images, like forests, animals, parties, ....
I'm not sure how that would stylistically figure into jazz.
