Yeah, Daimajin Kanon really feels a lot like the old Hibiki team getting to do all the things they wanted to do before they got forced to make it a Kamen Rider. The budget is just so much better, though, which makes a big difference in the appeal for me when they're doing stuff like the outdoor shots.
(If you're the sort of person who likes to read creator intent into things, you could interpret the developing plotline about Kanon's ex stealing her song and making a big hit out of it is an intentional reference to what happened with Takatera and Hibiki...)
