Good luck with the mod, Doordash4, and know you are not alone in your assessment of the post-refresh esthetics situation, front or back

Alas, while there are threads here about rear bumper and taillight conversion, I don't recall any about the front.
The one thing that appears to be certain is that the new headlight assembly is sufficiently different from the old one to make a swap very, very, very difficult, so no matter how much pain the bumper gives you, don't even entertain the idea of changing the headlights, try to work with the new ones and adapt the bumper somehow.
Also, I heard the new 2019+ hood had a slightly different curvature, so 2016-2018 bumpers are dicey, whether OEM or replica, you may need a hood swap as well for perfect lines and proper body gaps. Hope someone with a 2019+ can confirm or deny that before you invest into this project.
Oh, and before I forget,
