It helped design to drop and pick up the chain.
It's not just the ramp and pin, but also the teeth shape and the thickness of it.
On a true singlespeed chain, the teeth is symmetrical, whether on a double/triple, they are not (especially on modern chainring).
If you look closer you can see some of the teeth are not even;
You can probably get away with it, but it's best to eer on the side of caution by not suggesting this option.
I can't see why a ramped/pinned chain ring would make any difference. Surely it's designed to help moving between the cogs when "you" decide to shift.
