I'm wondering, does it make sense to say that an object has twice as much heat as another? Why?

It doesn't make sense.
In physics, the formal meaning of 'heat' is thermal energy **transferred* * between objects because of their temperature difference. The term 'heat' relates to energy transferred, not energy stored.
An object can have heat energy (thermal energy) but can't have 'heat'.
However you can say an object has twice as much heat energy as another. That's because heat energy is the kinetic energy of the random thermal motion of the particles. E.g. 2kg of ideal gas has twice the heat energy of 1kg of the same type of gas at the same temperature.
