I'm failing to see why you want to bring the switch leg 14/2 from the sw2 location to serve the bottom light.

My point is instead of switched power from the top 3 way ... take constant power to the top 3 way and connect the switched power of the 14/2 ( to the bottom light ) to the bottom 3 way common screw. Same thing just cleaner IMO.

Ah I see. I did the below three drawings before seeing your post and think I arrived at the same conclusion. I trust the "O" in the "IMO", but am curious what makes it cleaner to you.

Below are what I think are the configurations to consider. The biggest question to me now is whether or not it is ok code wise not having a neutral in the cable with the hots. I also wonder if I am worrying too much about trying to save one cable .

Cleaner may not be the best term to use. That usually means less wires and wirenuts. I should say I think it will make more sense later or to someone else to see the switched hot in the cable to the light connected to the 3 way switch at the bottom switch location and the power going to sw2 location and the white and red in the 14/3 will be used as travelers. This keeps all blacks in the wirenut and black to the 3 way switch common.. Again just my opinion.

No because each switch has its own power and return in one cable. You are not splitting the use of the wires across two switches. They are wired independent.

I prefer option 3.

I agree after having diagramed it - but with a couple of slight variations shown below to have the neutrals carried separately.

I like that also Jim but I thought the implication was difficulty in the switch leg routing from SW2 to the bottom light. In the end I guess it could be either way.

Honestly, I was just trying to save cable, but the cost of that one run isn't worth the complexity for the next guy to figure it out.

But it was an interesting consideration
