Save AssetBundle assets in Editor?

I'm looking for a way to save assets loaded from an asset bundle into the AssetDatabase in the Editor.
Can anyone help me out?

(In play mode) I can load the bundle, load the assets, and instantiate assets.
All I'd like to do is save them as asset files in the database.

 

https://docs.unity3d.com/ScriptReference/AssetDatabase.CreateAsset.html

idk if references are preserved though

 

I tried that and get a message like the following...

Couldn't add object to asset file because the GameObject 'tile_0_0' is already an asset at ''!
UnityEditor.AssetDatabase:CreateAsset(Object, String)
<LoadEm>c__Iterator0:MoveNext() (at Assets/Temp/LoadBundle.cs:63)
UnityEngine.SetupCoroutine:InvokeMoveNext(IEnumerator, IntPtr)

 

Call 'Instantiate' to instantiate the asset, then save the instantiate object to an assset.
