Your ideas seems very interresting to me,
and not at all childish or anything, it just
seems like plain fun. Me too has always adored
cartoons of any kind, so be it "Calvin & Hobbes" or my absolute favourite for now "Nemi"..
Anyway, once I become lucid I will surely try this
fascinating experiment out!
If you're childish, then so am I, and the most childish people are those who do not dare to admit it IMO.
Please tell me if you get any fun experiences with cartoons
