No, I think what you're suggesting is that the FW could be screwed onto the left side (the side where there normally isn't a drivetrain) without flipping it, and it would still freewheel in the normal direction. While that is true (provided that what is normally the outside face of the FW has been modified so that it will seat against the hub's thread shoulder, that the FW threads are throughgoing [not blind], and that there would be a way to later remove a FW thus installed) you would still have a FW that unscrews under pedalling load.

In other words, the solution you propose keeps the FW clutch correctly oriented by simply moving the FW laterally, rather than flipping it. Problem is, the wheel itself gets flipped, in effect, and its right hand thread now tightens toward the rear of the bike, even if it does mesh with the thread on the FW body irrespective of the FWs orientation (you can always flip a nut, as long as it isn't blind).

"There was some sort of automatic clutch mechanism in the hub that k icked out of one gear and into another as a certain rmp. A bike that's both fixed gear and not a single speed!"

Wouldn't it be as simple as putting the freewheel cog on the other way around so that the freewheeling is in the other direction, no need for left hand threads for the cog?
