Post Carousel - Possibility to include more than one Custom Post Type in the same carousel

I am looking for a way to include several different CPT’s (Custom Post Types) into one single Post Grid / Carousel, and then choose “individually” the post to show within the carousel. The reason I have made different CPT’s is that they aren’t sharing the same “element” template. I haven’t found other options than to make individual carousels for each post type. It would be nice if one carousel would include more CPT’s.
