Partially blocking the radiator will help regulate the temperature in the cooling system, keeping it at operating temperature when it's cold as balls out. Sure, warm the car up to operating temps, then go drive it at 70mph in 0* weather and watch it go back down.

No, you should not block the whole radiator, and no it won't help it warm up any if the thermostat is functioning properly, it will only help maintain that temperature.
I dont think you understand that there is ZERO NONE NO NO NO coolant flow when the thermostat is closed. When the coolant in the engine reaches opening temp it will allow a small amount of flow untill the temp goes back down.

I will take a video for you if you would like. In fact here is one I posted a few days ago of me having some fun on the interstate. Notice the temp (On the scangauge not the stupid stock gauge) before I did the pulls? That was after about 10 miles of 75 mph in the freezing south dakota weather. Feel free to look up the temperatures from the last week in rapid city SD. Its ****ing cold.
