Unit tech with 3 different models!

[Ardenian]

Hello, I would like to create hero tier for my map and therefore I need for elements 3 fitting models:

For example:

Tier 1 - Murloc
Tier 2 - Myrmidion
Tier 3 - Royal Myrmidion

Model 1 -> simple model
Model 2 -> detailed model
Model 3 -> powerful looking model

I know I can add attachments like wings or auras to units, but I would like to request other Tier Heroes/Units.

Another Example: Bloodelf Appendix Pack from General Frank

Tier 1 - A simple bloodelf warrior model ( not in his pack)
Tier 2 - Bloodelf Paladin Model ( lefthand site)
Tier 3 - Phoenix Avatar ( middle)

The most important point is Tier 3 Hero! he should look powerful, maybe godlike.

Models I mostly need:

- Fire Agility
- Fire Intelligence
- Advanced Spellbreaker Model ( Holy ( pls not HeroDarkHunter, he is my Tier 3))
- Nature Agility ( thought about dryad, but flower dryad as Agi Tier 3 ? Ranger would be an option, but what models as Tier 2, Tier 3 ? )
- Agi Corrupted/Dark
- Water Int ( or advanced Siren)

EDIT: oh, just to add, I don't want you to create new models ( although it would be awesome), I would like to hear ideas and models with free-source
