As for the pine if you wish lower branches they would likely be grafted on, unless you grew out a large sacrificial branch, then reduced it to initiate back budding blow the cit off point. Given the particular condition of this tree and the remaining branches the best bet over the shortest period of time would be grafting.
Having said that the tree appears very young and the distance up to the branching in not likely more than 8 to ten inches. So if that is the case I would use the movement, grow the sapling out into a larger Pine with a thicker base and develop the tree with apical leaders, alternating over the next decade or so.
How tall is the bare portion below the current branches?
