Post gallery as carousel

So I have this idea in mind: I would like to create custom page template, and whenever in post gallery is between tags, for example:

Lorem ipsum somethinginkgsd....

[carousel]
Gallery here
[/carousel]

I would like to convert this gallery to a carousel.

Creating carousel is fairly simple I guess. I just need something like get_post_gallery_images, but:

• get_post_gallery_images will only return first gallery in post


• this would still render gallery inside a post.

So my question is: how to get exactly the one gallery between [carousel] tags, and how to replace it?

Thank you a lot for any help!
