In one of my greatest moments I decided to move the attic switch from in the attic to downstairs as I'm always forgetting to turn it off and have to go back (yes, I'm a bit lazy).
In any case, I then was like... well what if I go in the attic and forget to turn it on (equally as bad of a scenario).
Attached is a diagram of my current setup. I haven't installed everything yet but the wires and the necessary electrical work downstairs has already been completed. Is there a way to add a 2nd light switch in the attic without modifying the "SW Downstairs" to a 14/3? The LINE is already in the attic. I'm 90% sure the answer is: "No"; but after being in a 90deg attic for a majority of the afternoon my brain isn't functioning at full capacity.
Please note: everything is in the attic except "SW Downstairs"
