No you cannot put in 60 amp breakers for overkill, unless you want to kill yourself and your family.

Breakers protect the wires in the walls from burning up.

If you have 14 gauge wire in a circuit, the maximum size of the breaker you can use is 15 amps.

12 gauge is 20 amp breaker.

Quite often the breaker sizes will add up to more than the main breaker/service size, but that is because most of those breakers are not using the full amount of amps. A 20 amp breaker might only be using five or ten amps at a time. You can only use 100 amps, which is quite a bit for a normal house without electric heat or electric tankless water heaters.

Breakers from an auction might not be good, have defects, were returned for a reason. There is no guarantee they will even trip to save you.
