If Spyderco did a bali I might bite, IF...the blade is 2" or so. If I can't carry it in CA then I will not buy it. Spyderco is really the leader in making 2" blades that seem like much larger blades, though I would foresee a Spydiebali as having a thinner blade than, say, the Salsa due to design.
I would not consider a balisong as a trick knife for Rambo wannabes. Actually, IMO a good balisong COULD make an awesome user knife which, when held open, is basically impossible to shut on your hand. Although requiring tight tolerances to make well, the mechanism overall seems fairly simple and extremely strong. Just like any type of knife, it's only as "evil" as the mind of the user.
I think a small (maybe 4" closed?) model with semi-wide spear-point, 1 7/8" blade with SS handles for handle weight, may be a good idea. For those who want a large one, have a larger one, too...but I would only consider the smaller one for myself.
