Non-pet scaling transmute for pets

Would be interesting to have some player stats scaling transmutes for pets that focus more on the effects than the pet damage itself.

Few Examples:
A variant of the blight fiend’s unstable anomaly transmute that scales with player damage with some additional effects.
Reap Spirit transmute that makes the player share the spirit’s power while it is alive.
Skellington transmute that makes them worthless damage wise but give you a bone shield (effect can be anything you want) when they die.

Basically, I’m looking for reasons to use pets in non-pet/hybrid builds, it’s something that’s severely lacking in my opinion.
