You might be able to make a stiffer, lighter kayak than the standard bairdarka, which are already very light compared to most yaks. But you'll be sacrificing the structural flexibility of the traditional boat.
Quote from skinboats.org:
"The structural flexibility is part of the secret to the performance of these boats, and also plays an important role in their durability because of the shock-absorbing quality."
The idea, as I understand it, is that the lashed joints allow stress in the members to pass from one side of the joint to the other; whereas a glued joint - being rigid - does not. So a glued boat might be stiffer but not necessarily stronger.
Also, I'm not sure that you're right about the ribs - the 9-day program to build the baidarka at skinboat.org has the ribs going in after the stringers are laid. Foir the aerolite boats, the forms constrain the stringers (temporarily), and the stringers constrain the ribs (permanently) - not sure I've seen any method where ribs are first, then stringers laid over them - if I understand you point correctly.
Bottom line - skinboats no longer use animal by-products, but otherwise follow traditional construction methods. You could take this further: use epoxy, kevlar strands, and a lighter fabric and wind up with a stiff and somewhat lighter boat (if you use thinner structural members). But I wouldn't necessarily take it into the types of conditions that the baidarka was developed for many years ago, where the structural flexibility is an advantage.
My $0.02 worth - by the way, I'm using the two-part urethane from skinboats.org to seal my snowshoe explorer 14 - hope to have that done this weekend.
