Maybe you could sell your husband on a separate man cave for his reloading and stuff. I know I would bite on that one. Of course a free standing sewing studio wouldn't be so bad either.
We only own 8 machines (my daughter likes to claim ownership too) and I can't think of any I want to part ways with so I know how you feel. I know some of the reason why I'm addicted to sewing machines but I don't understand why it's such a strong addiction.
There's still more machines I want to get. I'm still lacking a good free arm machine and I don't have one of the early 60s machines with all the chrome and knobs yet either. Those two are toward the top of my priorities, but I also like almost any older VS machine I see and I like the colorful paint jobs on the 1950s and 60s machines too. The list goes on. I'm almost grateful I don't have the room and must be selective in my choices.
