Have a Male Leopard Tort and want to get another Tort...possibly a RedFoot, but concerned how they will get along. Any Leopard owners out there have experience or suggestions in this regard?

I have a 7 year old male Leopard named Finn. I want to get another tort, preferably a RedFoot but I'm concerned about having another Tort in the house. I pretty much let Finn walk around most days and I know Leopards are very solitary and territorial. Are there any Leopard owners out there who have other Torts and can suggest a good situation? I'm in Chicago so they are indoors most of the year, that's why I let my Leopard walk around the house, so he has more room. It would be difficult to keep them separated all the time.
