So i could use a small amount of dry ice to match the weight of the item then make it look like the box has been tampered with, I will tape the box, then I will cut the tape to open it again then place a different coloured tape over that make it seem like the item was stolen in transit. < in theory does this sound like a viable EB?

No, you're thinking of the boxing method which Is completely unrelated.

In terms of the EB/missing Item method and In the case of the AirPods, you'd say that upon opening the box, the AirPods were missing.

My idea for the SB would've been to duct tape the rocks down to handle the problem of it getting shook and suggesting something has been tampered with.

and suggesting something has been tampered with.

^ Please elaborate on this further.

I have plans to SB an Iphone 13 eventually which i will use a dummy 1:1 instead.

The same can be done with the AirPods.
