i have also thought of a 6wd base but i am leaning for a 4wd with 8in stickes in the front and 8in omnies in the back this allows for the traction that you will need to go over the bumps it has its drawbacks you have yo go over stright othrwise you will just slide the back sideways. it is also very manoverable used the drive system in 2008
you can easily overcome the botoming out issues by putting a type of rub rail system on the robot like the sample ones had or moving your wheals front to back and even the size of them will help im open to sugestions
