WarCraft III - DDS Hack

Ok right... to clear somthing up, I dont need a MapHack, NameSpoofer any of that ShadowFrench stuff its a un-related hack...

Ok bear with me now...

On WarCraft III there is this "game" called DarkDeeds, basically you are a farmer and you must run away and build a farm and build an army to fight the randomly picked evil player... right.... If you win a game you get DDS (DarkDeedsScore) points, and if you get certain ammount of points you get special rewards that other people dont have like for e.g. if you have 500 points you might get a special item that makes u invisible for a short while. etc. etc. here is how it works...

If Player A Won the game he would get
+5 DDS Points
+A DDS Code = 559812-4141494 (or somthing)

When the game starts you have a lil' screen pop up where u must hit in your code. Right.

What i want to know is it possible to Packet Edit the packets, that say (At start of game) YOUR DDS SCORE IS "0" to YOUR DDS SCORE IS "500" or somthing (see attatched image)
