It's too radical and will cause people to instantly drop the project. This kind of change makes no sense even if you believe that Dedenne and Raichu are similar. You have already angered a number of people by making Raichu, a long-standing evolution of Pikachu, an evolution of Dedenne.

Unless you're inventing new Pokemon, altering a Pokemon's type will ALWAYS rub people the wrong way. The very fact that you're hacking Gen 6 is worthy of applause, but you've made a few very significant changes that a huge majority of people would never support and that will ultimately hurt the success of your hack. You posted it on /v/ because you wanted some attention, so I signed up because someone has to be That Guy. All Pokemon eggs now hatch extremely quickly.Pokemon who can mega evolve such as Mawile will have a 50% of carrying their respective mega stone.Pokemon who needed to be traded to evolve can now be evolved by alternate methods (usually by level up).HMs such as cut have had their typing changed and BP boosted A few moves themselves have been edited in terms of accuracy, type and BP.A lot of Pokemon have had their level up moveset edited to either match that of ORAS or improve those who didn't have a great moveset to begin with.Many Pokemon have had their stats slightly edited to make them comparatively viable to use Some have also had their typing edited such as Golduck who is now Water/Psychic.

Pokemon who had comparatively non-beneficial abilities have been given a new set entirely
