Ultimately yes, it is a template sensor.
It is a little more complicated as some of the sensors in the population might be unavailable or provide some outrageous, out of bounds, values or did not change for a large amount of time.
Some of the question that might be raised: what value do we use for the unavailable sensors or the ones that don’t provide relevant info? Should we approximate to the values of the available sensors? Should we use some default values (like 25 degrees (Celsius 
))?
