With his business acumen, I am sure he could go almost anywhere and run most businesses. That would be an awesome combination! BTW, The Most Interesting Man in the World was on TOS... and survived being a redshirt! Maybe that is why he is so "Interesting"!
Perhaps they could hire Andrew Robinson? I'd love to see Garak advertising these suits. "You're going to like the way you look. The Order guarantees it!"
