Pure splash weapon

[avv]

Is it possible to make a weapon that does pure splash damage without direct hit bonus? Or reduce the ammount that indirect hit damage is lowered?
I'm trying to make grenades do more damage when thrown next to the enemy, without making their direct hits too powerful.

Not that I know of, any difference between direct and indirect damage is hard coded and would be universal for all weapons.
