The replaceable blade sounds good. I like the idea........... ya' break a tip (and who hasn't?), you replace the blade. Simple!
The changeable inserts sound like a weak link in the chain though. Especially since permanently (yeah, right) mounted scales have always fallen apart on me.
Now, with that said, I do think that a full side "Facade" might work. You can make the Main liner out of TI, then attach full sided Face-plates to the sides, much like scales on a folder. The face-plates themselves can be Skeleton or Insert type, and made from Steel, brass, TI, G-10, or whatever. Attachment could be via torx screws at top and bottom, or sides.
The inside face of these plates can also be grooved (or drilled) to accept small, movable counter weights. A must if you're offering different blades and scales as an option....... because balance IS important.

Another thing that could use improvement is the Tang pin, and it's relationship to the handles.
The small contact area that most tang pins provide is murder on the average handle material. I think a larger contact surface area would not only extend the life of a Balisong, but would also make for a tighter lock-up when open.
My thought is this:
Normally, the tang pin is done by drilling a whole, and inserting a small section of rod.
I think a better method would be, to notch (or groove) that end out and insert a disk (horizontally) into it. That would give more contact area, and be stronger than your typical Tang pin of today. Again, a set screw would hold it in place.
And please, please, please.............. I'm beggin' ya' here...... DON'T make it latchless!!!!
At the very least, make a standard latch available to those of us that consider it a
MUST HAVE.
