Fusion change

Hello, I would like to talk about mergers and their changes

namely, I want to make it possible to change the merger for some time without using the second item,
one of my ideas is to replace a fusion of one category for a given number of stabilizers with another fusion
e.g. 1 fusion change would cost 10 stabilizers

stabilizers would become more expensive in a moment, so players would replace some of the most necessary items, and the rest would be a waste of money, unless these rich people wanted to have a perfect garage again.
