Since there are dwarves in Goblin Slayer, I think it's logical goblins do attack dwarves as well.
In Hobbit the movie, there are scenes where the dwarves are fighting in goblin dungeon, and getting captured by goblins. These are awesome scenes of dwarves vs goblins, and Thorin the Dwarven King is about to get gay anal sex from goblins.
I don't think it's suitable for this game, since this game is having serious feature creep. Too many things to add in such a short time, I afraid it might increase your work burden, maybe add dwarf content next game?
Here's a video of Gandalf (Wizard with strong melee skills) and a group of dwarves slaying goblins, and the goblin king.
