Make 2 units and use abilities like morph from terrorblade or the druid morphing ability. That ability lets you choose the normal and alternate models.
If more than one shapeshift, using abilities based on different base orders would do the trick.

Morphing Units
**************
Morphing has problems, but here is what we have: A list of abilities you can base your morph abilities off.
Abilities for Self Morphing
- Metamorphosis - Demon Hunter
- Destroyer Form - Obsidian Statue
- To make this both ways, go to "Data - Morphing Flags" and uncheck "Permanent"
- Strom Crow Form - Druid of the Talon
- Bear Form - Druid of the Claw
- Burrow - Crypt Fiend or Scarab
- Fiend and Scarab burrows, do not stack directly but act oddly the second time one is cast.
- Robo-Goblin - Goblin Tinker
- Stone Form - Gargoyle
- This ability has some problems I have yet to find a solution to, it crashes at times and I have yet to identify the reason.
-Submerge
- Only works for naval units
Abilities for Morphing Others
- Polymorph - Sorceress
- Go to "Stats - Targets Allowed" to pick the "Others"
- Call to Arms - Town Hall/Keep/Castle
- This ability has some problems I have yet to find a solution to, it crashes at times and I have yet to identify the reason.
- Hex - The Troll Guy (sorry!)
As much a reference to me as to you, here are the quotes of what people have identified as problems or solutions with morph and I will attempt to use these to enhance this tutorial.
