The 44-year-old former middleweight and light-heavyweight champion, nicknamed 'The Executioner', returns to his home town on Wednesday for the first time since 2003 to tackle Ornelas at the Liacouras Centre at Temple University.
Hopkins has not fought since defeating Kelly Pavlik in October last year, but he is already overlooking Ornelas and discussing the prospect of a meeting with Haye, who took the WBA heavyweight crown from the 7ft 2in tall Nikolai Valuev last month.
Hopkins is due for a re-match with Roy Jones Jr next March and is aiming to emulate his achievement of becoming a middleweight-turned-heavyweight champion in 2010 at the age of 45.
He said: "I'm going to look good, then I'm going to finish off Roy Jones Jr and then I might become heavyweight champion in 2010."
On a potential meeting with Haye, he added: "Anything is possible, when a guy beats a guy they call 'The Giant' then things happen.
"Just think outside the box. Think who he's been fighting and who he's going to fight and second of all, what weight did he come from and how did he do it.
"So at the end of the day, when you put these things together, you say to yourself, 'is this something that I would buy?' - 'is this something that I will watch?' and whoever wins or loses you will say 'yes I will buy and watch it, because it's interesting'.
"I've seen things happen in boxing and that's all you need to make a good chemistry.
"Never rule anything out with me. People have ruled me out a lot of times in my life, and that's been my biggest motivation.
"December 2 starts a marathon for me, a marathon of super-greatness and the boxing world are going to be scratching their heads. I'm going to have their attention next year."
