In order to get a thicker branch on a bonsai fig it would mean getting the branch to grow faster and have more leaves than other branches on the tree. Another way is to fuse several branches together to achieve greater thickness.

The three branches were fused into one and created a branch that is heavy enough for this trunk
One of the most interesting styles of bonsai is the root-over-rock design. Simply a tree is designed to grow over a rock. There are many variations to this form but Ficus do very well in this configuration as their roots are aggressive and will cling to a stone if given a chance.
One caution is to use a normal form of a fig and not a dwarf form. The dwarf forms grow more slowly and it will take longer for them to anchor on the stone and to form good branching that will be needed to bring the design to life.
Ficus microcarpa ‘Taiwan Medium Leaf’ in a recent photo – more detailing and refinement of the branches is needed
Five years ago the tree was attached to the rock and it was buried deeply and allowed to grow freely
This is a Ficus microcarpa ‘Taiwan Medium Leaf’. It is one of the smaller microcarpa forms and is much slower growing. Initial work attached the tree to the stone and I buried the stone quite deeply. Growth was allowed with little trimming for several years to get the tree to stabilize and adhere to the rock. In later stages the branches and sub-branches will need to be defined to bring out the best in the bonsai.
