It's prob doable. I do remodeling construction and have a property management company, so I have some skills. It's just my opinion, but you'd be chasing a $5 bill with a $20 bill by the time you were done. And if it wasn't 'factory' looking, you'll take a big hit when you go to sell. Like houses...bad remodeling stops sales in their tracks. Good remodeling only makes things sell faster, not for more.
I have a 30rds which has a larger banquette and I, personally wouldn't attempt what you want to do. The wife and I spend most of our 'inside' time at that doing our whatevers, not just eating and I'm fairly certain I'd get divorce papers for even thinking of changing it.
Experience is what you get when you don't get what you want.
