Hey! Sequel paths to many of the existing paths are planned! (BE will continue on Hyper Expansion path, Growth will continue on Giantess path, etc.)
The minigames on those will also probably be remix/hard versions of the normal minigames.
Sequel paths will only be implemented later in development, once all the other main paths are added, since those are meant to be end-game content!!
Failing a path to unlock another semi-related inverse path is already a mechanic that exists with the Ass Expansion route, which will be expanded to other paths in the future!!
