Is there any possibility that this mod could be modified to work with create's item vaults?

I am not sure, I will need to look into what is happening with Create's vaults to get an understanding of the exact problem and cause of it. Currently, this mod is specifically patching the sophisticated storage mod to make it freeze the inventory, similar to what happens when you apply packing tape to a sophisticated storage inventory (in fact that is what this patch is doing right before VS relocates the inventory when you assemble a ship).
I will need to dig into what Create is doing when a vault block is relocated. Also, vaults have the added complexity of the fact that they are a multi-block structure that I will need to figure out.
So no promises, but I will try to find some time to take a look into this to see if I can solve it.

(btw, sorry for it taking so long for me to reply on this, I have been extremely overloaded at work for the last few months, and I haven't had any time for side projects like this for a while)
