Interior help desired - We need more sleeping space

[Curtis-79MH]

My 79 MH has had the sofa/bed and fold away table removed and replaced with facing bench seats and a table in between (ala Winnebago). Across the aisle is a plush chair and an AS credenza type storage cabinet.
Anyone out there done any interior modifications or have an idea that might help me get some more sleeping space? The two single beds are great for the kids, but my wife and I need a place to sleep. I could make the table and bench seats convert into a bed, but before I do I thought I'd check with the forum!
This is my first stab at the forum and I look forward to learning and working on my motorhome. Thanks to Peter 79-MH for pointing me in the right Airstream direction.
I'll try to include a picture.
