If you have a 4 cm squares board the answer is clear yes, there is enough space between diagonal models or models and the wall.
if you play on the original board, the answer is quite clear no - the models are superposing with their arms and weapons.
This is the original board. In my game, no shooting between diagonal standing models.
Spears and other diagonal close combat weapons work diagonal between two models, though. This is inconsistent, i know. Maybe i have to rething that one. Later, after the quest.
You can use your result against the orc if you want.
And Rumseeker kills the Goblin. No difference in the result, except for the positioning of the models.
