Question is: If I was to replace the closed drive line with an open drive line, Would this eliminate clutch chatter? also, since the torque tube acts also as a brace for the rear end, if it was removed how would one brace the rear end?

This is not a particularly viable option, as you would have to convert the rear suspension to longitudinal rear springs (like a 48 pickup). Yes, the torque tube is also a torque arm, and simply eliminating it requires a complete conversion to a hotchkiss style rear suspension. Would it eliminate clutch chatter? Probably, since the dual rear springs would cushion the torque reaction at clutch engagement; but at what cost? The clutch chatter problem is one of controlling "feedback". As the clutch is engaged, the torque tube pushes the transmission/engine assembly forward, which causes a change in the position of the clutch arm relative to the clutch housing. The idea of the "slingshot" bracket, and the anti-chatter rods was to reduce that fore-aft movement. The problem is that there is a second torque reaction that is twisting the /transmission/engine assembly on its rubber mounts. The anti-chatter rods, or "slingshot" bracket do nothing to restrain this movement which also affects the position of the clutch arm. Ford attempted to mitigate this by switching from the clutch arm/clevis set up to a blade/trunnion cross shaft in 1940. I believe it helped. If the clutch is "grabby", the motor mounts are soft, or the driver hasn't learned to accommodate the "nature of the beast", we all live with clutch chatter. In summary, I believe it is part of the EFV8 Driving Experience.
