Pitcher Plant and Torchflower Attracting and Repelling Hostile Mobs

I just want the pitcher plant and torchflower to have a bit more purpose, and having the pitcher plant attract hostile mobs like skeletons, zombies, spiders, and creepers makes sense; since its real world counterpart attracts things like mice and frogs, and having the torchflower repel those same mobs (without emitting light) also could improve gameplay, like if someone wants a dimly illuminated base, but doesn't want mobs to be surrounding them constantly, then they'd go through the whole sniffer process, adding a bit of mid-game adventure; I also think it should attract them as far as it takes for them to notice the player, so around 16-40 blocks.
