You can do pretty much whatever you want - just recognize that some bulkheads 
require more strength than others.

If you are using the bulkhead in lieu of footpegs, the bulkhead should be 
stronger than if you are just using it as a waterproof wall between the cockpit 
and a dry compartment.  If you are mounting a foot-operated pump on it, you 
would similarly need a stiff, strong bulkhead.

Dave's advice is good.  I'd suggest that two layers of 8 oz with nothing in 
between would be good if the bulkhead is in a low-stress environment.  It would 
be reasonably strong but a tad flexible and possibly lighter than with the matt 
layer (less resin).  3mm okoume with one layer of 8 oz on each side would be 
almost bombproof.
