Say your friend allowed you to take apart and see the internal workings of a nice SUV you liked. If you studied everything outside and inside the car intensively, could you create a hotwheels-esque replica with full-working motors and everything? The Minor Conjuration feature states (PHB pg. 116):
Starting at 2nd level when you select this school, you can use your action to conjure up an inanimate object in your hand or on the ground in an unoccupied space that you can see within 10 feet of you. This object can be no larger than 3 feet on a side and weigh no more than 10 pounds, and its form must be that of a nonmagical object that you have seen. The object is visibly magical, radiating dim light out to 5 feet.
So, what I want to do is conjure the SUV I studied, and cast Enlarge/Reduce on it.
Enlarge/Reduce (PHB pg. 237):
You cause a creature or object you can see within range to grow larger or smaller for the duration. Choose either a creature or an object that is neither worn nor carried… Enlarge. The target’s size doubles in all dimensions, and its weight is multiplied by eight. This growth increases its size by one category–from Medium to Large, for example…
Since the car is 3 feet in any given dimension, I could compare it to a halfling, whose size states:
Halflings average about 3 feet tall and weigh about 40 pounds. Your size is Small.
Meaning that the car is therefore the Small size and able to be transformed into a Medium size.
TL;DR, can I do it like Hank Pym and Enlarge a small conjured car into a Medium car and drive around in it? (at least for 9-10 rounds at a time, or using some sort of spell extension technique to extend that 9-10 rounds)
