Just thinking out loud... If you put spacers under the trim piece to raise it, it'll probably leave a gap at the windshield.
If you don't mind risking the part since your alternative is to cut it anyhow, you could shove a couple 1" blocks of wood in there to force it up, and then nail it with a heat gun to soften it, then let it re-form with the new shape...? Not sure if the hood would interfere with it after that, although maybe the foam seal would deflect enough so that the hood doesn't push the trim back down to hit the ZL1 lid again.
