In general I would recommend you take a gander at Mailankas Psi-Wars on his blog.
Not dragon ball related per se but it shows a philosophy I agree with in action. It is called "Create don't convert."

Essentially whatever the case, you will have to make changes to fit this thing into your system. You might as well give it an original name and pull on some other elements/your headcanon and declare that as the truth for your game.
His Psi-Wars series in general is just an excellent showcase of iterative design and this creation over conversion principle.
He applies it to Star Wars, you do to Dragon Ball.
