Using Elementor with Imperio theme


I’ve been thinking of downloading Elementor to help the ease of designing our website pages. I’ve used OptimizePress3 and when I want to use those pages, my previous pages become distorted because I have to change to the specific theme for OP3. I’m worried the same will happen if I download elementor.

My question is, will Elementor require its own theme or will it be able to work while Imperio is active and its just an “addon”. Will the Elementor pages be able to be mixed in with our regular Wordpress pages without messing anything up?
