  The built-in behaviour of dropping one item on another is to combine them. If no combine interaction exists, you should be able to hook into the OnInventoryCombine custom event to alter their positions in Player's Inventory collection.

  Something along these lines:

  using UnityEngine;
  using AC;
  
  public class ItemSwapper : MonoBehaviour
  {
  
      void OnEnable () { EventManager.OnInventoryCombine_Alt += OnInventoryCombine; }
      void OnDisable () { EventManager.OnInventoryCombine_Alt -= OnInventoryCombine; }
  
      void OnInventoryCombine (InvInstance invInstanceA, InvInstance invInstanceB)
      {
          var invCollection = KickStarter.runtimeInventory.playerInvCollection;
          int indexA = invCollection.IndexOf (invInstanceA);
          int indexB = invCollection.IndexOf (invInstanceB);
  
          invCollection.Insert (invInstanceA, indexB, OccupiedSlotBehaviour.Overwrite);
          invCollection.Insert (invInstanceB, indexA, OccupiedSlotBehaviour.Overwrite);
          PlayerMenus.ResetInventoryBoxes ();
      }
  
  }

  It works great!

  All I had to do was make InvCollection playerInvCollection public in RuntimeInventory.cs

  Thanks so much!

  No need for that - replace the script's use of it with PlayerInvCollection
