I got a two ideas, Making Solo Cowboy bebop style, by replacing the score with the anime’s score and re-grading it to make it look more like Bebop, Adding and changing sound effects, changing the aspect ratio to 4x3 and others
And two, replacing the entire score with Rockin roll and metal,
Music by Guns & Roses, Corn, Ozzy, Pink floyed, Metallica and others
Please do the Cowboy Bebob edit.
