have you burnt the dead wood or added an ink to lime sulpher or the sorts? i would consider using a wood hardner on this as ficus wood can get pulpy quite quick under humid wet conditions

on the other hand it is quite possible that the wound will roll over quite quickly and you will find yourself with a different sort of trunk.
its going well other wise. i would let it grow out quite solid for a while now to get some branch structure oppurtunities

then defoliate and wire once you got choice and remove anything else that wont be part of the overall design of the tree
good luck and enjoy
