The idea is well and good, the main problem I have with major ideas like this is the scope of the game. If the process was quicker and I had the time to work on big content things like this I'd be more open to it. Realistically though, adding events related to your idea would likely double the time between updates. Due to the nature of the game and how it's being made, everything is rather exact so in order to turn Amelia into a predator we're talking all new sets of images regarding internals, externals, swallowing, along with all the dialogue to describe what's happening.
I will be making this game open-source at the end once I'm done with it, so if someone likes where this game ends as a starting point and wants to add onto it they'd have my blessings. I need to be careful with my time though, so I won't personally be adding this.
