Greg, pinching the wire is still going to happen as the "duct" is still inside the hatch weather seal. And, that doesn't address the stress problems.
I am aware lots of folks do what you're planning on doing, however, you end up with more headaches and expense than if you took the time to drill a hole. Since you're adverse to doing so, is the reason I suggested the hood seam. In the real world (especially when using FM), the performance difference is moot.
