I have two concerns which may not have shown themselves to you yet.

Denim is a very unique fabric it continues to shrink over its entire life span. With pants you have legs in them to pull them back into shape. This is why jeans seem to mold to your body.
In kilts all the pleats will become shorter and shorter. At the topstitching you may develop wrinkling just as you do on the side seams of jeans. Unless you iron the kilt A LOT within a short time denim has a tendency to start to look like a tutu.

My other concern is with the two lines of stitching. Experience has shown that topstitching 1.8" from the pleat edge is good. Any further and the pleats tend to curl. Usually outward.
If you goal is to create a garment that will have curling pleats similar to a Utilikilt then this is not a problem. If your goal is to create a garment that has pleats more refined then this curling will be very bad unless, again, you iron the kilt after each washing.
This curling will be further emphasized by the revK pleating. That style of pleating is very prone to curling as kilts made this way seldom have Steeking.

Just some food for thought.
