Not that it hasn’t been done, but I am not aware of anybody who has changed all of their stainless trim to a black-out look by using vinyl.
I would be concerned about the vinyl edges remaining firmly attached; seems adhesion would certainly be a problem with the over the door drip-rail SS.
A word of caution regarding the windshield rubber gasket trim. Do not attempt to pull that trim out. It must be installed and removed as an assembled unit - Glass, gasket and trim - due to the method that the trim is anchored, using a J hook, into the rubber gasket.
