In my opinion after seeing the pictures, the hood die will not help. The die, by what I can decipher would help mostly around the curved profile of the hood.
This is the manufacturer of the die. not much information and good images are lacking.http://sunsdahltooling.com/index.php?option=com_virtuemart&Itemid=88&vmcchk=1&Itemid=88
In my opinion, a repair on that hood, would take the patience of Job- for a journeyman, let alone a novice.
Your concern about minimizing body filler on this hood shows your lack of experience and you would be best advised to start with a hood with a lot less damage.
