SUBSIM Radio Room Forums - Question about torpedos

Hi, i love all the silent hunter series especially number 4 and ive been playing them properly for a while now, but i want to do some changes to my game, for instance

Change 1:
Nuke torps ----> by this i mean hugely explosive which will send a large splash into the air an turn ur opponent into steaming bits of fire,

Change 2:
Infinate ammount of torps ----> well that 1 is obvious no need for explaining i guess

Change 3: (only if change 1 cannot be done)
any way to change the ammount of damage torps can do, such as mod the explosion radius and damage it deals, speed etc

please give me ?/10 if its possible
