The modern Finn Classic is a nice set up with multiple options for chambering and spare barrels, it would be pretty easy to put together a heavy O/U 9.3x74R double rifle, 12ga/30/06 combo and a 12ga O/U travel set.
There are any number combo guns available, I have ones set up for coyote hunting BRNO12ga/22 HP-12ga/12ga and a Bernardelli12ga/5.6x50R Mag.
The search is almost as much fun as shooting one.
A starting place.
