The best choice for you now is to reverse him all that you can and feed the SA (to 10) with other Hercule. Take an SR and raise the SA to 9 and dokkan aweken him until you can rise your current Hercule's SA. Also open the 4 paths while he is reversed.

Once he is SA10 and 4 path open you hace to take back him to LR and raise another SR Hercule SA10 to LR and train each other to obtain a Hercule LR SA20.
