I've done slips all the time in 182s with full flaps, just pitch down more, in fact most people do not do this enough because they are trying to replicate their "normal" landing pitch while slipping, and they tend to get slow. I'll even go as far to say that most people should not land these with 40 degrees of flaps and they do not make an approach that is appropriate. Why are you going to follow the VASI at 40 degrees of flaps and 12" of MP? How does it make sense to power in at a high-AOA and high power seting during landing? How much extra power will you now have when you hit some wind shear or downdrafts? If you are going to use the 40 degrees you need to come in at an AOA and speed that are approrpiate (usually going to be pretty steep). This airplane is a drag-queen with 40 degrees, but you can still slip. Don't get slow, think about your descent rate and transitioning to normal landing later on. Never had it "pitch down" on me like you describe in any situation. Think about it, how would that be possible?

You can find a lot of crazy things stated by examiners, less by inspectors, and less depending on the experience, knowledge and ability of whomever you are talking to. Realize that examiners are kind of out there "on their own" by contract from the FAA. They sometimes have some pretty interesting/crazy ideas. Think about their reasoning and do some research.
