I just want to dispel that thought right now. LEGO doesn't take fan suggestions for their themes on that kind of a scale. It'd go nowhere and would be a waste of everyone's time. In addition, that is not the point of G3. It's not another wasteful "Bring back BIONICLE" campaign. So no, we will never pitch it to LEGO.
Also, regarding the question, I can make my favorite food something I don't like, right? So if I went "My favorite food is Brussels sprouts," then boom. No more.
(For the record, I have never have Brussels sprouts... that I can remember, at least).
