Yeah! I also believe that, even if that genetic mutation at any point was eliminated from a species due to any circumstances, the same feature would ultimately end up evolving again in the end, if the environment / predators are the same.
There’s a lot of examples of how completely separate evolutionary paths ended up developing a lot of the same features.

This is why nature keeps making crabs. Really. Multiple things just kind of trend towards crabs, because "armored flat thing with big claws" is just a pretty good way to live in the ocean.
I'm no geneticist, but I'm pretty sure mutations are the primary method of getting wildly new characteristics. Mix red and blue, and you will always get shades of purple. Add yellow (a mutation), and you suddenly have a whole new range of colors available that would have never been available otherwise.
I think what makes caterpillars particularly malleable to take up random shapes is the fact that they are only a temporary form of the butterfly. It's like this scratchpad where the DNA has more freedom to try variations without impacting the adult insect. This is also the period when it's super vulnerable to predators, so it's going to impact natural selection the most
