I think it can be done. You would need two Z-bars for the flat table. I think I would try to re-use the hinge hardware on your current grill.
The latch mechanism and pivot on a Silver B ( your current grill) is in my opinion easier to use than the sliding style on an x000, and you already have the hardware. Often the hardware for the swing up table on the older Genesis x000's are rusted apart.
Another thought is to just clean up the thermoset. There are good suggestions for making it look almost like new. I have this on my to-do list but haven't gotten around to it. The rehabber's here will have the best advice so I'll defer to them.
I mention this as the lid handle will still be plastic as well as the end caps so your grill will be a mix of wood and plastic.
And, I like the plastic end trim on the silver. LH side works well as a handle to move the grill around and the RH side has tool holders on it as well as the dropped section holding the bar of the condiment tray.
good luck and share your progress on this.
