Gift of Hedone: Anni the Anvil (Upgrades)?

Hello you wonderful deviants, So Anni the Anvil will be your personal Anvil throughout your Journey, I was wondering if you think we should keep her the same throughout, or do you think she could potentially be "Upgraded" as you progress through the story?Upgrading certain "features" making them bigger, even Jigglier etc maybe some thing about needing to upgrade her to a point to eventually interact?Im open to suggestions, or if you think she perfect the way she is, thats a completely valid response and answer.
