Apart from the above, if you open the details panel of a ship (bottom left side), you see icons for all weapons, and below them the current/basic number (so 1/3 Lance Turrets would mean 2 are destroyed). Also mouseovering the icons will show you current range.
After the changes to boarding hoes live, this will already be handled and no additional delay is needed.
The delay the OP would like to see will already be implemented, just not between hulking and scuttle, but between boarding and hulking.
The over-time nature of boarding will give you time to start moving away before the ship is hulked, thrus making it easier to dodge the scuttle.
