Issue with my theme and the Course Press Pro Plugin

Love the course press pro plugin but it does not look so great with my theme. I am currently using Avada but might switch back to Scribe now that we got the black line issue fixed. Will the theme switcher plugin work for course press pro where it only uses that theme while in Course presspro?
Also will there be any issues with locking down pages on the membership plugin if I switch in between themes?
