I highly, highly doubt that is going to be an issue. Steven Davison has done plenty of productions with elements like these that have never had a problem. If the "suits" had a problem with the content, Steven would have had to have cut them already. Contrary to what some may believe, but a villain element to a parade (or any entertainment production), that includes fire or "darker" effects, has been just fine in many Disney entertainment productions.
When it comes to cuts...the only thing that typically has to be worried about is special effects. Esp. with TDO. They aren't exactly the best executive team when it comes to keeping everything up to show quality standards. And with Steven Davison (WDI-CE) productions, it's a hell of a lot more than just old floats and a character flood. His productions are very intricate and elaborate, and very technology and performance driven.
As of right now, I doubt there is anything to worry about.
