How to best handle entity references that should be duplicated upon instantiation?

Ok so I have this use case:

• I have a "Gun" component
• The Gun has an Entity field that represents the "BulletPrefabEntity"
• The Gun also has an Entity field that represents the "BulletSpawnPointEntity"

I begin by doing the following in order to convert my Gun to entities for fast instantiation:

Code (CSharp):

1. Entity startingGunPrefabEntity = GameObjectConversionUtility.ConvertGameObjectHierarchy(PlayerStartingGunPrefab, World.Active);

And afterwards, in game, I Instantiate the Gun like so:

Code (CSharp):

1. Entity gunEntityInstance = entityManager.Instantiate(startingGunPrefabEntity);

Now I have a problem.
Both the "BulletPrefabEntity" and the "BulletSpawnPointEntity" refer to the original converted entities. This is what I want for the "BulletPrefabEntity", but it's not what I want for "BulletSpawnPointEntity". The bullet spawn point should be duplicated in order to represent the one attached to the gun I instantiated.

I understand how it makes perfect sense that "Instantiate" does not automatically duplicate entities like I just described, but I was wondering how you guys handle cases like these. Would you make a custom instantiation function for the gun? Is there some kind of [DuplicateEntityReference] attribute I can put over Entity fields that should be duplicated? Etc, etc.....

Instantiating from the GameObject prefab and letting the conversion do its thing would be a solution to this problem, but it is waaaaaay more expensive than instantiating from the already-converted entity so I'd prefer to avoid it
