Would you like more involved Evolutions?

A lot of Pokémon 'dex entries describe Pokémon doing some rather involved processes to evolve, such as Slowpoke having a Shellder clamp on it to become Slowbro or Slowking, or Magnemite, Koffing, or Metang gathering/fusing with more of their kind. But with few exceptions, most of these are ignored in-game in favor of more standard leveling up.

But how many of us would be okay with, like, or even prefer getting/having to go though those processes, as a game mechanic? To say, go to an area where Koffing gather and fight another one to fuse into yours to make a Wheezing, or actually making your Slowpoke get Clamped by a Shellder to evolve.
