Heat accelerates the cure of epoxies in general, so reducing the catalyst is intended to slow down a reaction that you think will be problematic,

Epoxy "hardener" is not a catalyst. It is a molecule that reacts with the epoxy component to crosslink the epoxy polymer. It is an essential component of the formula. The formulation is designed to have an optimum amount of crosslinking to get optimum properties. Changing its ratio will be like altering the amount of cement added to sand and rock to make concrete.

Can you change hardener ratio? Sure and the result will be something that gets more of less hard. Maybe hard and tough enough for the application. Furniture is always a good lab in which to do chemistry experiments on adhesives and finishes. ;)
