Yes Supanimal, they must be a bit suspect in solid waves.
Piros, I think Dean Snow & Woogie get their shafts from the same place, and there a 2 different diameter CARBON shafts that sleeve together perfectly. Could be the "back-bones" of your replica 2 piece board. Would be easy to add them onto some carbon flat plates.... then come up with a carbon bolting arrangement.
For an 8'11 / 9'0, I would also consider doing the join between 5'0 and 6'0, not in the middle.
The carbon shafts are so light, and so strong, I would consider doing 2 (a pair) of carbon shaft stringers.
Then you can fly J* into Melbourne Avalon, which is only 40-45 mins from Bells !!
