How to mount those hinges to the flap without drilling a holes? How to prevent flap falling inside (down) ?
Epoxy or JB Weld is your friend: no holes to drill. Ducting via Coroplast and duct tape, or aluminum foil tape. With push-pull cable (from bike shop) adjust cowl flap angle. Add (with JB Weld) small lip to keep flap from falling down. Cut one more slot beyond the 3 you were already gonna cut.

How to cut? Dremmel tool? Laser? Router? Hi pressure water jet? This would require a practice run on a scrap piece of metal, using tape to protect the paint surface. Properly done, you would only need to use touch up paint to color and protect the edges after the cut, to prevent rust on the exposed metal edges. Probably best to remove the part from the car and do the work on a bench. Probably worthwhile to ask somebody who does custom body work for input, or artist who works in sheet metal. Probably best to position the hinge on the cut line before making the cut, to make sure all is in perfect alignment after the cut.
