What do you suggest if I'm currently taking 180 mg of oxyneo and want to switch to hydromorphone for pain.?

Why?? Oxyneo is an effort to provide adequate amounts of the needed pain drug (oxycodone) in a form that is resistant to abuse, both by crushing and snorting, and by smoking. If you want to switch, i wonder what you are trying to get from the medication. You need to talk to your prescriber about your issues, and consider whether there is now an underlying addiction developing.Dilaudid is highly abusable.
