Does adding an extra Akuma or miraculous to an already transformed Hero Enhance their physical’s

This is something that I always thought about when I was younger up to now, seeing as the miraculous is already enhance their physical capabilities, when they transform with one,they gain the base abilities of strength,speed,and durability. So taking that into account, I thought that Adding one of the other miraculous is/unifiying it would enchance their Physical abilities I don’t know if this is true and now has lots of times in the show when they unify there powers and fight an miraculous, we order, normally The person with the unify miraculous is the person I think that would absolutely dominate The miraculous w wielder that only has one Because I thought that they would be strong by two times at least their normal strength without the other added miraculous or akuma but as seen in the show with fights like (shady bug vs ladyfly) and (snake noir vs the mind controlled Miraculouse holders)they just seem to have the same strength and so on so what you guys think?
