lightGallery and JustifiedGallery will apply to wordpress standard [gallery]?

Hi! I am evaluating a purchase of the pro features.
A requirement is the possibility to use JustifiedGallery + lightGallery to style the standard [gallery] without using the proprietary shortcode.
This because I am using Enhanced Media Library to create dynamic gallery contents based on image tags and categories.
Is it possible? It’s not so clear from the info on the website “It is really easy to replace your old WordPress gallery or add lightbox gallery support for your existing thumbnails”.
