I have too much free time on hands. Reading the different topics that deal with direct mount vs. adapters, and progressive 2Vs vs. Synchronous 2Vs, I think I had an Epiphany (not Religious). 
I have what I have, and will continue to tinker with my progressive Weber on an adapter until I win the Lottery/Power Ball.
When I looked at some of the direct mount setups, I was struck by the fact that a progressive carb should be mounted with the Primary at the center, and the Secondary outboard for most even distribution. However, a Synchronous 2V would best be mounted with the throttle shafts on the fore-aft axis, so that each barrel is actually feeding a trio of cylinders, and the center acts as a Plenum.
My intuitive suggestion (for consideration) to those considering a 2V swap: For economy, use a progressive carb mounted on an adapter. For more power, use a synchrous carb directly mounted to the log.
