That is what he said he did on movie models back then, he also lowered the engines closer to the belly of the aircraft. When i get to that stage i will ask him again and go from there.
It also means that new fabricated structure may have to reinforced now to accommodate new former/bulkhead in there on which fan units and engine will be mounted. Now i am thinking on terms or tune pipes!, on pusher set up engine and pipes are in front of the fan unit vs tractor set up, i really don't want to have pipe sticking out of the exhaust nozzles!, i may move the former at the LE of the fin where it is mounted on the fuselage meaning move then ahead some inches...
