What gooseneck problem are you refering to ?

Personally I would strongly prefer to have the boom above the attachment points of the push rods as then the rig can rotate fully around the mast which is very advantage (performance) when sailing deep. It also is a safety feature as any kid can let the rig weathervane completely when surprised by a squall or something.

A freehanging boom (possible with a fork at its mast end) is possible and most easy solution
