It is a great initiative, I would like cosmetics to have some use beyond appearance, but I share opinion with many comments, you have to know how to implement them, the improvements could be 1.5%, 3%, 5%, something small, but that is a complement to the percentage that already exists, that is, if you are using a magmar with body flame to hatch the eggs, Well, this increases by 3% if you carry the complete set of fire.
