Swapping gears from front to back
I joined this forum to ask this question. Your running a 16 tooth gear in the back and a 36 at the crank. Say, hypothetically, you could swap the gears, putting the 16 tooth at the crank and the 36 tooth gear on the rear hub.
Would this effect the way it performs at all, and if so, how?

Running a single speed set up. 16 tooth gear in the back and a 36 at the crank. Say, hypothetically, you could swap the gears, putting the 16 tooth at the crank and the 36 tooth gear on the rear hub.

You can't be serious.........try it, and find some steep hills if you succeed.

Purely following this practically impossible hypothetical scenario, this will change the gear ratio from 36:16 (= 2.25) to 16:36 (= 0.444), potentially allowing you to spin up some fairly steep ascents. Gear ratio is how many revolutions your rear wheel makes per revolution of the crank shaft. Back in the real world, you should consider potentially replacing either (a) the existing chain ring with another chain ring with a different number of teeth (e.g., 32T) and/or (b) the existing rear cog with another rear cog with a different number of teeth (e.g., 18T) to adjust the gear ratio rather than trying to swap the two existing components.

The answer without worrying about the specific numbers, is that your legs would need to move much much much faster to reach the same speed as with the original setup. It might even be difficult to maintain balance travelling at such a slow speed.

I don’t believe the SS cog and a direct mount chainring use the same interface so a swap is not possible.
But it is possible if your crank uses a direct mount chainring and you could find a direct mount 16t chainring, which is doubtful, or have one machined. I think you can find a 26t.
If your crank is a 4 bolt, then you can go down to 30t.
Something has prompted you to ask, I’m guessing the 36/16 gearing is too tall. Depending on the setup, the easiest change would be swapping out the rear cog to an 18t to 24t.
