My opinion is that your lever gun is a perfectly suited home defense gun, its advantage in your situation is that you are extremely comfortable with it and should be able to handle it in the dark and under stress.
Depending on where you live, if you have the unfortunate need to use the gun in self defense, the police will take the gun after the incident. You may or may not get it back. I live in Mass, If I have to use a gun in self defense I don't plan on ever seeing it again. It seems like this gun means a lot to you, and you may want to consider how you will feel if your gun is caught up in legal limbo. I have a glock and an AR for home defense, fairly cheap, easily replaceable, and since they are plastic guns they have no soul haha.
If you do not live in a state run by idiots who think guns automatically make you a criminal, ignore the second part of this post
